[0177] Salts and solvates, e.g., hydrates, of the Compounds of the Disclosure can also be used in the methods disclosed herein.
[0178] The present disclosure encompasses the preparation and use of salts of Compounds of the Disclosure. Salts of Compounds of the Disclosure can be prepared during the final isolation and purification of the compounds or separately by reacting the compound with an acid having a suitable cation.

In light of the foregoing, any reference to Compounds of the Disclosure appearing herein is intended to include Compounds of the Disclosure as well as salts, hydrates, or solvates thereof.
[0179] The present disclosure encompasses the preparation and use of solvates of Compounds of the Disclosure. The term solvate as used herein is a combination, physical association and/or solvation of a compound of the present disclosure with a solvent molecule such as, e.g., a disolvate, monosolvate or hemisolvate, where the ratio of solvent molecule to compound of the present disclosure is about 2:1, about 1:1 or about 1:2, respectively. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances, the solvate can be isolated, such as when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid. Thus, solvate encompasses both solution-phase and isolatable solvates. Compounds of the Disclosure can be present as solvated forms with a solvent, such as water, methanol, and ethanol, and it is intended that the disclosure includes both solvated and unsolvated forms of Compounds of the Disclosure.
[0180] One type of solvate is a hydrate. A hydrate relates to a particular subgroup of solvates where the solvent molecule is water. Preparation of solvates is known in the art. See, for example, M. Caira et al, J. Pharmaceut. Sci., 93(3):601-611 (2004), which describes the preparation of solvates of fluconazole with ethyl acetate and with water. Similar preparation of solvates, hemisolvates, hydrates, and the like are described by van Tonder et al., AAPSPharm. Sci. Tech., 5(1): Article 12 (2004), and A. L. Bingham et al., Chem. Commun. 603-604 (2001). A typical, non-limiting, process of preparing a solvate would involve dissolving a Compound of the Disclosure in a desired solvent (organic, water, or a mixture thereof) at temperatures above 20 C. to about 25 C., then cooling the solution at a rate sufficient to form crystals, and isolating the crystals by known methods, e.g., filtration. Analytical techniques such as infrared spectroscopy can be used to confirm the presence of the solvent in a crystal of the solvate.
[0181] The use of the terms a, an, the, and similar referents in the context of describing the disclosure (especially in the context of the claims) are to be construed to cover both the singular and the plural, unless otherwise indicated. Recitation of ranges of values herein merely are intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. The use of any and all examples, or exemplary language (e.g., such as) provided herein, is intended to better illustrate the disclosure and is not a limitation on the scope of the disclosure unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosure.
[0182] The term wt/wt % as used herein refers to the mass of one component in a composition or blend, e.g., a composition comprising a Compound of the Disclosure and one or more elastomers; or a Composition of the Disclosure and one or more fillers; or a blend comprising two or more elastomers, etc., divided by the combined mass of all components in the composition or blend, times 100. For example, the wt/wt % of a Compound of the Disclosure in a composition comprising 1 kg of the compound, 1 kg natural rubber, and 2 kg of synthetic rubber, is 25 wt/wt % (1 kg/4 kg=0.25100=25 wt/wt %). The wt/wt % of a Compound of the Disclosure in a composition comprising 1 kg of the compound and 1 kg of carbon black is 50 wt/wt % (1 kg/2 kg=0.20100=50 wt/wt %). The wt/wt % of a Compound of the Disclosure in a composition comprising 1 kg of the compound, 1 kg natural rubber, 2 kg of synthetic rubber, and 1 kg of carbon black is 20 wt/wt % (1 kg/5 kg=0.20100=20 wt/wt %). The wt/wt % of natural rubber in a blend of one or more elastomers comprising 20 kg natural rubber and 30 kg synthetic rubber is 40 wt/wt % (20 kg/50 kg=0.40100=40 wt/wt %).

[0193] In another embodiment, a Composition of the Disclosure comprises a Compound of the Disclosure and one or more elastomers.
[0194] The term elastomer as used herein is a polymer with viscoelasticity (i.e., having both viscosity and elasticity) that typically has low intermolecular forces, low Young's modulus, and high failure strain. Elastomers can typically be cross-linked by heating in the presence of one or more cross-linking agents, a process called curing or vulcanization. Rubber is one type of elastomer. Non-limiting types of rubber include natural rubber (NR), synthetic rubber, and blends thereof. The term natural rubber as used herein refers to a naturally occurring elastomer that can be obtained from Hevea rubber trees. Non-limiting types of synthetic rubbers include unsaturated rubbers, saturated rubbers, rubbers with fluoro and fluoralkyl or fluoralkoxy substituent groups on the polymer chain (FKM), silicone rubbers (Q), and blends thereof. Non-limiting examples of unsaturated rubbers include polyisoprene rubber (IR), butyl rubber (IIR), polybutadiene rubber (BR), styrene-isoprene-butadiene rubber (SIBR), styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), chloroprene rubber (CR), ethylene propylene diene rubber (EPDM), and blends thereof. These unsaturated rubbers undergo cyclization and crosslinking reactions that lead to hardening of the aged part. As oxidation occurs, these vulcanizates harden and eventually become brittle products. Partial oxidation of vulcanizates leads to losses in performance when used in applications such as vehicle tire sidewalls. Saturated rubbers are rubbers that do not contain CC unsaturation and include, but are not limited to, acrylic rubber (ACM), chlorinated polyethylene (CM), chlorosulfonated polyethylene (CSM), polychloromethyloxiran (CO), ethylene-ethyl acrylate copolymer (EAM), epichlorohydrin rubber (ECO), ethylene propylene rubber (EPM), ethylenevinylacetate copolymer (EVM), rubbers with fluoro and fluoralkyl or fluoralkoxy substituent groups on the polymer chain (FKM), silicone rubber (Q), and blends thereof.
[0195] In some embodiments, the natural rubber comprises rubber derived from an alternative rubber plant. The term natural rubber comprises rubber derived from an alternative rubber plant as used herein refers to a naturally occurring elastomer that can be obtained from non-Hevea sources. In some embodiments, the alternative rubber plant is Parthenium argentatum (guayule) or Taraxacum kok-saghyz (Russian dandelion).
[0196] In some embodiments, the one or more elastomers further comprises recycled rubber. The term recycled rubber as used herein refers to an elastomer that has been reclaimed from scrap materials such as used tires.

Synthesis of 2,2,4,8-tetramethyl-N-phenyl-1,2-dihydroquinolin-6-amine (Compound 1)
Step 1
##STR00137##
[0252] A 250-mL round bottom flask fitted with a stir-bar and a thermometer was purged with N.sub.2, then protected with N.sub.2 blanket (the outlet was connected to a base trap containing about 250 mL of 1 mol/L NaOH). Glacial acetic acid (18.0 mL) was loaded to the flask, then stirred was started. 3-Methyldiphenylamine (4.8 mL; 27.9 mmol) was added (no exotherm was observed). Once 3-methyldiphenylamine was fully dissolved, aq. 37% HCl (2.9 mL; 35.0 mmol HCl) was added over 40 seconds. The temperature rose to 26 C. The flask was chilled with ice-water bath. Once the temperature reached 5 C., a solution of sodium nitrite (1.93 g; 27.9 mmol) in DI water (5.6 mL) was drop-wise added such that the temperature was kept below 8 C., over a period of 9.5-10.0 minutes. A dense liquid phase separated. The ice-water bath was removed. The reaction mixture was stirred at 7-20 C. for 35 min to complete formation of the nitrosamine intermediate. The flask was chilled with an ice-water bath. Once the temperature reached 10 C., aq. 37% HCl (5.8 mL; 70.0 mmol) was added over 2.5-3.0 min (no exotherm was observed). The ice-water bath was removed. The reaction mixture was stirred at 10-25 C. to complete formation of the desired product. A red solid separated after approx. 30 min. After 120 min (total reaction time), the mixture was diluted with DI water (76 mL), whereupon a slurry formed. The solid was collected by vacuum filtration (Buchner-filter paper) and washed with DI water. An aliquot of the damp solid analyzed by LC-MS/UV (260 nm) indicated the presence of 87% desired product. The damp solid was triturated with EtOH (45 mL). The slurry was filtered under suction. The obtained solid was dried under vacuum at 40 C. for a couple of hours. Yield=5.1 g (86% of the theoretical yield with respect to 3-methyldiphenylamine) as a brick red powder. The crude material was involved in the next step without further purification.
Step 2
##STR00138##
[0253] To a 250-mL flask fitted with a stir-bar and a thermometer were loaded 3-methyl-4-nitroso-N-phenylaniline (see Step 1; 5.0 g; 23.6 mmol) and EtOH (100 mL). The mixture was stirred under N.sub.2 protection (most of the solid dissolved; a brown solution was obtained). Ammonium sulfate (3.11 g; 23.6 mmol) was added in one portion (no exotherm was observed). The mixture was stirred for approx. 1 hour at room temperature. The flask was chilled with a cold tap water bath. Sodium borohydride (1.80 g; 47.6 mmol) was portion-wise added over approximately 2 minutes. The reaction mixture was stirred with the water bath for 10 min (the temperature rose to 32 C.). The water batch was removed. the temperature rose to 35 C. About one hour later, additional NaBH.sub.4 (0.48 g; 12.7 mmol) was added. The reaction mixture was stirred for additional 1.5 hours. Additional NaBH.sub.4 (0.89 g; 23.5 mmol) and ammonium sulfate (3.49 g; 26.4 mmol) were added (at 2.5 hours reaction time). The reaction mixture was stirred for additional time. The total reaction time was 3 hours. DI water (66 mL) was slowly added. The mixture was diluted with ethyl acetate (200 mL). The organic phase was washed with aq. 1M NaOH (3100 mL), with brine (100 mL), dried over MgSO.sub.4, filtered, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The resulting black oil was dried on a rotary evaporator (55 C.; <5 mbar) for 15-20 minutes. Yield=3.2 g (68% based on 3-methyl-4-nitroso-N-phenylaniline) as a black gooey material (Intermediate Compound 1-I). An aliquot of Intermediate Compound 1-I was characterized by LC-MS/UV (260 nm) as well as .sup.1H and APT .sup.13C NMR spectroscopy, as shown in
Step 3
##STR00139##
[0254] To a 250-mL flask fitted with a stir-bar and a reflux condenser were loaded crude 3-methyl-N.sup.1-phenylbenzene-1,4-diamine (Intermediate Compound 1-I; 83.4% pure; 3.1 g; <15.6 mmol), and acetone (6.5 mL; 87.9 mol). The mixture was stirred under N.sub.2 protection. Zinc(II) triflate (679 mg; 1.87 mmol) was loaded in one portion. The reaction mixture was heated (oil bath=62 C.). After 16.5 hours, additional acetone (3 mL; 40.6 mmol) was added. The total reaction time at 62 C. was 25 hours. The reaction mixture was stirred at room temperature for about 48 hours. The obtained black liquid was diluted with a mixture of hexanes and ethyl acetate (5 mL). The obtained solution was loaded into a 41 mm diameter chromatography column previously prepared with silica gel 60 (approx. 23 cm height) and eluent (10% ethyl acetate in hexanes). The column was eluted with 10% ethyl acetate in hexanes. Several fractions (approx. 30 mL each) were collected and characterized by silica gel TLC (10% ethyl acetate in hexanes). The portions containing the dots at Rf=0.35 (desired product) were collected, combined, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). Note that mesityl oxide shows as a dot at Rf=0.40 and was not separated from the product at that stage. The resulting yellow liquid was dried on a rotary evaporator (65 C.; <5 mbars) for 10 min. Yield=0.34 g as a yellow viscous material (Compound 1). An aliquot of Compound 1 was characterized by LC-MS/UV (260 nm) as well as by .sup.1H and APT .sup.13C NMR spectroscopy, as shown in

Synthesis of 8-methoxy-2,2,4-trimethyl-N-phenyl-1,2-dihydroquinolin-6-amine (Compound 7)
Step 1
##STR00140##
[0255] To a 250-mL round bottom flask fitted with a stir-bar and a thermometer was loaded 3-methoxydiphenylamine (11.8 g; 59.2 mmol) and glacial acetic acid (36 mL). The mixture was stirred under N.sub.2 protection (the outlet was connected to a base trap containing about 250 mL of 1 M NaOH). Aq. 37% HCl (18 mL; 217 mmol HCl) was added by portions over a couple of minutes. 3-methoxydiphenylamine dissolved during the addition of aq. HCl. No exotherm was observed. A light-yellow solution was obtained. The flask was chilled with ice-water bath. Once the temperature reached 4-5 C., a solution of sodium nitrite (4.169 g; 60.4 mmol) in distilled water (12 mL) was gradually added over a period of 17-18 min such that the temperature was kept under 10 C. The resulting dark-red mixture was stirred between 2 C. and 9 C. for 30 min, then the chilling bath was removed. The reaction mixture was stirred without external cooling or heating (2-22 C.) for 2 h 40 min, whereupon a dark red solid separated. Distilled water (80 mL) was added and the slurry was stirred for a few minutes. The solid was collected by filtration under suction, then rinsed quickly with distilled water and EtOH (50 mL). Drying under vacuum at 40 C. for about 2 h, then at room temperature overnight, yielded 7.8 g (57% of the theoretical with respect to 3-methoxydiphenylamine) of a dark red powder. An aliquot of this material was characterized by LC-MS/UV (260 nm). The crude material was involved in the next step without further purification.
Step 2
##STR00141##
[0256] To a 500-mL flask fitted with a stir-bar and a thermometer were loaded 3-methoxy-4-nitroso-N-phenylaniline (See Step 1; 7.8 g; 34.2 mmol) and EtOH (210 mL). The mixture was stirred under N.sub.2 protection (some solid remained insoluble; a red slurry was obtained). Ammonium sulfate (9.05 g; 68.5 mmol) was added in one portion (no exotherm was observed) and the mixture was stirred for approximately 1 h at room temperature. The flask was chilled with a cold tap water bath. Sodium borohydride (3.31 g; 87.5 mmol) was portion-wise added over a period of 16 min such that the temperature was kept under 28 C. (frothing occurred). The reaction mixture was stirred with the water bath for 110 min, during which the reaction mixture turned black. The water bath was removed. Approximately 10 min later, distilled water (150 mL) was slowly added and the mixture was stirred for a few minutes. The mixture was diluted with ethyl acetate (450 mL) in a separatory funnel containing distilled water (100 mL) and aq. 1 M NaOH (100 mL). After shaking and decanting, the aqueous layer was discarded. The organic layer was washed with aqueous 1 M NaOH (100 mL) and brine (100 mL), dried over MgSO.sub.4, filtered, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=55 C.). The resulting black oil was dried on a rotary evaporator (55 C.; <12 mbar) for 1 h. Crude yield=6.2 g as a black gooey material. The crude material was dissolved in toluene (10 mL). The obtained black solution was loaded into a 71 mm diameter chromatography column previously prepared with silica gel 60 (8 height) and eluent (50% ethyl acetate in hexanes). The flask was rinsed with 50% ethyl acetate in hexanes (5-10 mL). The column was eluted with 50% ethyl acetate in hexanes. The portions (100 mL each) containing the desired product (TLC 50% ethyl acetate in hexanes; dots at Rf=0.7) were collected, combined, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The resulting black/purple viscous liquid was dried on a rotary evaporator (55 C.; <2 mbar) for 15-30 min. Yield=4.3 g (58% based on 3-methoxy-4-nitroso-N-phenylaniline) as a dark viscous material (Intermediate Compound 7-I). An aliquot of Intermediate Compound 7-I was characterized by .sup.1H and APT .sup.13C NMR spectroscopy, as shown in

##STR00142##
[0257] To a 250-mL flask fitted with a stir-bar and a reflux condenser were loaded 3-methoxy-N.sup.1-phenylbenzene-1,4-diamine (Intermediate Compound 7-I, see Step 2; 4.3 g; 20.1 mmol), acetone (8.9 mL; 120 mol), and zinc(II) triflate (0.727 g; 2.00 mmol). The mixture was stirred under N.sub.2 protection and heated (oil bath=62 C.) for 40.5 h. The substrate took about 2 h to initially dissolve, then a dark homogenous solution was obtained. Upon cooling to room temperature, the obtained black liquid was loaded into a 41 mm diameter chromatography column previously prepared with silica gel 60 (30 cm height) and eluent (20% ethyl acetate in hexanes). The flask was rinsed with additional acetone (3-4 mL). The column was eluted with 20% ethyl acetate in hexanes.

The fractions containing the dot at Rf=0.6 (desired product) were collected, combined, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The resulting powder was dried on a rotary evaporator (55 C.; <3 mbars) for 20 min. Yield=2.5 g (42% of the theoretical with respect to 3-methoxy-N.sup.1-phenylbenzene-1,4-diamine) as an almost-white crystalline powder (Compound 7). An aliquot of Compound 7 was characterized by LC-MS/UV (260 nm) as well as by .sup.1H and APT .sup.13C NMR spectroscopy, as shown in

Synthesis of 2,2,4,8-tetramethyl-N-phenyl-1,2,3,4-tetrahydroquinolin-6-amine (Compound 2)
##STR00143##
[0258] To a 20-mL vial was loaded a stir-bar, 2,2,4,8-tetramethyl-N-phenyl-1,2-dihydroquinolin-6-amine (Compound 1; 1.07 g; 3.84 mmol), and MeOH (12 mL). The mixture was stirred. Once Compound 1 was fully dissolved, aqueous 37% HCl (0.32 mL; 3.9 mmol) was added. A deep purple solution was obtained, which was added to a 300-mL Parr autoclave with MeOH (130 mL) and 10% Pd on C (Sigma, 0.25 g). The reaction mixture was maintained at 21 C. (water circulator). The autoclave was charged with H.sub.2 until 52 PSIG was attained. A modest exotherm ensued (up to 24 C.), which subsided after 10 minutes. The total reaction time was 75 minutes (the pressure decreased from 52 to 45 PSIG over the first 10 minutes, then plateaued at 44 PSIG the rest of the reaction time). The mixture was filtered through Celite S and the cake was rinsed with methanol. The combined filtrates (dark blue solution) were kept under N.sub.2 protection overnight. The volatiles were stripped under reduced pressure (rotary evaporator; water bath=50 C.). The resulting dark solid was taken up in a mixture of ethyl acetate (50 mL) and aqueous 1 mol/L NaOH (40 mL). The 2-phase system was magnetically stirred until complete dissolution of the solids over a period of 10-15 minutes. The 2-phase system was transferred to a separatory funnel. After shaking and decanting, the aqueous phase was discarded. The organic phase (brownish solution) was washed with aqueous saturated NaCl solution (40 mL), dried over anhydrous MgSO.sub.4, filtered, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The resulting dark oil (0.95 grams) was dissolved in 10% ethyl acetate in hexanes (approx. 4 mL). The obtained solution was loaded into a 1 inner diameter column previously prepared with silica gel 60 (70-230 mesh) and 20% ethyl acetate in hexanes. The height of wet silica gel in the column was approx. 6.5. The column was eluted with 20% ethyl acetate in hexanes. The fractions containing the dot at R.sub.f=0.6 (silica gel TLC; 20% ethyl acetate in hexanes) were collected, combined, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The obtained oil was dried on the rotary evaporator (water bath=55 C.; <3 mbars) for 1 h 40 min to yield 0.81 grams (75% with respect to Compound 1) of 2,2,4,8-tetramethyl-N-phenyl-1,2,3,4-tetrahydroquinolin-6-amine (Compound 2) as a light-brown oil. Compound 2 was characterized by .sup.1H and .sup.13C APT NMR spectroscopy, as shown in

[0259] To a 250-mL round bottom flask fitted with a stir-bar, a thermometer, and a reflux condenser was loaded 2-methyl-4-nitroaniline (5.0 g; 32.9 mmol), anhydrous grade toluene (38 mL), and 2-methylbut-3-yn-2-ol (4.8 mL; 49.5 mmol). The mixture was stirred. Dry N.sub.2 was bubbled through the solution for a couple of minutes, then the system was protected with N.sub.2 blanket. Copper(II) chloride (450 mg; 3.35 mmol) and copper(I) chloride (330 mg; 3.33 mmol) were sequentially added to the flask. The reaction mixture was heated to reflux for 44 hours. Upon cooling to room temperature, the mixture was vacuum filtered through Celite S (disposable 0.2-micron polyethylene frit) and the flask/cake was rinsed with copious amounts of toluene. The filtrate was stripped of volatiles under reduced pressure (rotary evaporator; water bath=65 C.). To the residue was added 10% isopropanol in hexanes (20 mL) and the obtained slurry was magnetically stirred overnight. The yellow solid was collected by vacuum filtration (disposable 0.2-micron polyethylene frit) and rinsed with hexanes (20 mL). LC indicated about 75.1% purity at that stage. The solid was washed with 50% isopropanol in hexanes (20 mL). LC indicated about 82.3% purity at that stage. The solid was washed with 25% MeOH in hexanes containing a few drops of isopropanol (20 mL). LC indicated about 88.0% purity at that stage. Finally, the solid was washed with 50% MeOH in hexanes containing a few drops of isopropanol (20 mL) and dried under vacuum at 45 C. for about two hours to yield 1.9 grams (26.5% with respect to 2-methyl-4-nitroaniline) 2,2,8-trimethyl-6-nitro-1,2-dihydroquinoline (Intermediate Compound 119-I) as a yellow solid. Intermediate Compound 119-I was characterized by .sup.1H NMR spectroscopy, as shown in

[0260] To a 300-mL Parr autoclave was loaded 2,2,8-trimethyl-6-nitro-1,2-dihydroquinoline (Intermediate Compound 119-I; 0.949 g; 4.35 mmol), toluene (130 mL), acetophenone (1.00 mL; 8.57 mmol), and sulfided 3% Pt/C frm (Johnson Matthey; 0.134 g wet). The reaction mixture was heated to 120 C. Once the temperature was reached, the autoclave was continuously fed with H.sub.2 (set pressure=300 PSIG) for 2 hours. The reaction mixture was allowed to stand at room temperature under N.sub.2 protection overnight. LC-UV/MS analysis indicated incomplete conversion at that stage. The reaction mixture was heated to 150 C. under 300 PSIG of H.sub.2 for approx. 3 hours. LC-UV/MS analysis indicated better conversion at that stage. Finally, the reaction mixture was heated to 170 C. under 350 PSIG of H.sub.2 for 3 hours. LC-UV/MS analysis indicated almost complete conversion at that stage. The mixture post reaction was filtered under suction through Celite S. The cake was rinsed with minute amounts of isopropanol. The volatiles were stripped under reduced pressure (rotary evaporator; water bath=65 C.). The resulting light-brown liquid was diluted with hexanes (1 mL). The solution was loaded into a 1 inner diameter column previously prepared with silica gel 60 (70-230 mesh) and 10% ethyl acetate in hexanes. The height of wet silica gel in the column was approx. 22 cm. The column was eluted with 10% ethyl acetate in hexanes, then 20% ethyl acetate in hexanes. The fractions containing the dot at R.sub.f=0.2 (silica gel TLC; 10% ethyl acetate in hexanes) were collected, combined, and stripped of volatiles under reduced pressure (rotary evaporator; water bath=50 C.). The obtained oil was dried on the rotary evaporator (water bath=55 C.; <5 mbars) for 2.5 hours to yield 0.78 grams (61% with respect to Intermediate Compound 119-I) of 2,2,8-trimethyl-N-(1-phenylethyl)-1,2,3,4-tetrahydroquinolin-6-amine (Compound 119) as a clear light-brown oil.

[0261] To a 250-mL round bottom flask fitted with a stir-bar and a reflux condenser was loaded 3-methyl-N.sup.1-phenylbenzene-1,4-diamine (1.8 g; 9.08 mmol) and acetonitrile (15 mL). The mixture was stirred under N.sub.2 protection. Ethyl pyruvate (2.1 mL; 18.9 mmol) and iodine (0.070 g; 0.276 mmol) were sequentially added to the flask. The reaction mixture was heated (oil bath temperature set to 60 C.). The temperature was maintained for 90 minutes. Upon cooling to room temperature, sodium sulfite (0.26 g; 2.06 mmol) was added and the mixture was stirred for 30 minutes. The volatiles were stripped under reduced pressure (rotary evaporator; water bath=50 C.). The crude material was diluted with 50% ethyl acetate in hexanes (10 mL). The obtained slurry was loaded to a 41 mm inner diameter column chromatography prepared with silica gel 60 and eluent (50% ethyl acetate in hexanes). The height of wet silica gel in the column was approx. 11. The column was eluted with the same eluent. The fractions coming out (50 mL each) were analyzed by silica gel TLC (50% ethyl acetate in hexanes). The fractions containing Compound 120 were collected, combined, and stripped of their volatiles under reduced pressure (rotary evaporator; water bath=50 C.). Further drying on the rotary evaporator (50 C.; <5 mbars) for approx. 2 hours afforded 2.7 g of diethyl 2,8-dimethyl-6-(phenylamino)-1,2-dihydroquinoline-2,4-dicarboxylate (Compound 120) as a dark oil. Compound 120 was characterized by .sup.13C APT NMR spectroscopy, as shown in

Oxidative Induction Time (OIT) Performance of Compounds of the Disclosure
[0262] The oxidative induction time (OIT) of selected Compounds of the Disclosure was evaluated. OIT is measured according to a procedure carried out in a differential scanning calorimeter (DSC; TA Instruments, Q200). In this procedure, a sample is held in a cell and heated under a nitrogen atmosphere to a preselected temperature. Oxygen (O.sub.2) is then introduced to the cell and the length of time before the onset of degradation, as observed by the initiation of an endothermic process in the DSC trace, is measured.
[0263] 0.5 wt % of a Compound of the Disclosure, N.sup.1-(4-methylpentan-2-yl)-N.sup.4-phenylbenzene-1,4-diamine (6PPD), or no antidegradant (blank) was mixed with polyisoprene and heated isothermally at 150 C. or 160 C. in O.sub.2. The OIT in minutes is shown in Table 2. As indicated by the data in Table 2, Compounds of the Disclosure demonstrate antioxidant activity compared to the blank control.

As shown in Table 3, the rubber sidewall compounds are a 50/50 blend of natural rubber and butadiene rubber with a carbon black of the N500 series. Example #1 is a sidewall compound comprising Compound 1. A control sidewall compound comprising no antidegradant was also prepared. According to American Society for Testing Materials (ASTM) test method D5289, vulcanization properties of all the compounds were characterized by a moving die rheometer (Alpha Technologies MDR 2000), also known as MDR, at a temperature of 160 C. for 60 minutes. The oscillation strain and frequency were set to 0.5 C. and 1.667 Hz, respectively. The MDR test results are summarized in Table 4.

Example 8
Antiozonant Performance of Compounds of the Disclosure in Sidewall Compounds
[0264] The rubber sidewall compounds prepared in Example 7 were cured at 160 C. to a state equivalent to its T90+2 min time. The ozone test specimens were died out from vulcanized tensile sheets by using a die followed the American Society for Testing and Materials (ASTM) D1329 standard. The ozone test specimens were stored in an ambient environment for more than 24 hours prior to antiozonant performance testing in an ozone chamber, which was maintained at an ozone concentration of 10+2 parts per hundred million (pphm) and 40+2 C. The ozone test specimens were simultaneously relaxed and extended within ozone chamber under dynamic conditions. The ozone test specimens were alternately relaxed and extended to 25% strain at a rate of 90 cycles per minute during dynamic exposure. Exposure was in increments of 24 hours followed by at least one hour of relaxation after removal from the ozone chamber and prior to measurement of force at a strain of 100%.
[0265] Antiozonant performance of antidegradant formulated compounds were evaluated by percentage of force retention. The percentage of force retention is defined by equation 1.
Percentage of force retention=F/F.sub.0*100%:Equation 1:
wherein F.sub.0 is the force at a strain of 100% prior to ozone testing and F is the force at a strain of 100% after samples are aged in ozone chamber for 16-hour cycle at dynamic exposure. Higher percentage of force retention is an indication of better antiozonant performance of an antidegradant compound incorporated in the vulcanized rubber compound.
[0266] The force of aged and unaged ozone test specimens was measured by using a tensometer (Alpha Technologies, 2000) at a strain of 100%. The percentage of force retention for the sidewall compounds were calculated and plotted as a function of ozone aging time in

Example #la is a tread compound comprising Compound 1. A control tread compound comprising no antidegradant was also prepared. According to American Society for Testing Materials (ASTM) test method D5289, vulcanization properties of all the compounds were characterized by a moving die rheometer (Alpha Technologies MDR 2000), also known as MIDR, at a temperature of 160 C. for 60 minutes. The oscillation strain and frequency were set to 0.5 C. and 1.667 Hz, respectively. The MVDR test results were summarized in Table 6.
