EXPERIMENTAL

(177) General Synthetic Methods:

(178) The compounds of the present invention, or their pharmaceutically acceptable salts, can be synthesized using the methods described below in schemes 1-6. It will be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and work up procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that optimum reaction conditions may vary with the particular reactants or solvents used, but such conditions can be determined by the person skilled in the art, using routine optimization procedures. Additionally, one skilled in the art will recognize that in many cases, these compounds will be mixtures of stereoisomers that may be separated at various stages of the synthetic schemes using conventional techniques, such as, but limited to, crystallization, normal-phase chromatography, reversed phase chromatography and chiral chromatography, to afford single enantiomers. For all the protection and deprotection methods, see Philip J. Kocienski, in Protecting Groups, Georg Thieme Verlag Stuttgart, New York, 1994 and, Theodora W. Greene and Peter G. M. Wuts in Protective Groups in Organic Synthesis, Wiley Interscience, 3rd Edition 1999. The schemes 1-6 are representative of methods useful in synthesizing the compounds of the present invention. They are not to constrain the scope of the invention in any way.

(180) Scheme 1 illustrates a method for preparing compounds of Formula 1. In which L is S, O, N or a bond; R.sub.1 is H, C.sub.1-C.sub.6 alkyl, NH.sub.2, or CN; R.sub.2 is aryl, heterocycloalkyl or heteroaryl; R.sub.3 is C.sub.1-C.sub.6 alkyl, OR.sub.1; R.sub.5 is alkyl, H; R.sub.6 is alkyl, H; R.sub.5 and R.sub.6 together with the atom or atoms to which they are attached, can combine to form a monocyclic or polycyclic C.sub.3-C.sub.12 cycloalkyl or heterocycle.

(181) Compound int-1 is treated with aryl or alkyl boronic acids or esters or salts (where L is a bond) under suitable metal catalysts (such Pd.sub.2(dba).sub.3, or the like), suitable ligands (such as dppf, or the like), suitable bases (such as Cs.sub.2CO.sub.3, or the like), suitable solvents (such as DMF, or the like) to provide a product of int-2. In other cases, where the L of Formula 1 is O, N or S, compound int-1 was reacted with corresponding phenols, thiophenols, thioalcohols or amines under suitable metal catalysts (such as CuI, Pd.sub.2(dba).sub.3), suitable ligands (such as TMEDA, XPHOS, Xantphos, or the like), suitable salts or bases (such as Cs.sub.2CO.sub.3, K.sub.3PO.sub.4 or the like), suitable solvents (such as DMF, dioxane or the like) to provide a product of int-2. The reaction temperature is ranged from 80 C. to 140 C., and the reaction takes 1-24 hours to complete. Compound int-2 reacted with amines with or without bases (such as DIPEA), in suitable solvents (such as DMF, NMP or the like) under the temperature range from 80 C. to 140 C. to offer compound of Formula 1. If desired, further transformations may be performed to provide a product of Formula 1-2. For example, the compound of Formula 1-1 wherein R.sub.3OH may be subjected to an alkylation reaction to provide a compound of Formula 1-2.

(182) ##STR00158##

(183) Scheme 2 illustrates a method for preparing compounds of Formula 1-3. Compound Int-1 was first halogenated to provide intermediate Int-2. The activated chlorine in Int-2 was displaced by an amine to afford Int-4. Int-4 reacted with an aryl amine or phenol to provide target compounds of Formula 1-3 (R.sub.3H).

(184) For the compounds of Formula 1-3 where R.sub.3 was OH, Int-6 was regioselectively hydrolyzed to provide Int-3, and then followed by substitutions and couplings to offer target compounds.

(185) Deprotection steps can be incorporated either before or after the coupling reactions.

(186) ##STR00159##

(187) Additionally, the compounds of Formula 1-3 can be synthesized using an alternative way, as illustrated in Scheme 3. The order of reaction steps may alter. Coupling reactions may occur before the amine displacement.

(188) ##STR00160##

(189) Scheme 4 illustrates a method for preparing compounds of Formula 1-4. Int-1 was reacted with an aryl amine or phenol in the presence of a suitable metal catalyst (such as CuI, or the like), a suitable ligand (such as TMEDA, TMHD, or the like), a suitable salt (such as K.sub.3PO.sub.4, or the like) and a suitable solvent (such as dioxane or the like). The reaction proceeds at a temperature ranged 80 C. to 140 C., with the reaction time from 1-24 hours. Int-2 reacted with an amine in the presence of a suitable coupling reagent (such as BOPCl, or the like), a suitable base (such DIEPA, DBU, or the like), and a suitable solvent (such as DMF, THF or the like). The reaction proceeded at temperature 80 C. to 130 C. with 1-24 hours to finish.

(190) ##STR00161##

(191) Alternatively, as illustrated in Scheme 5, the order of reactions can be modified to change the overall synthesis to allow for variations at different positions of the molecule at different stages of the preparation. For example, in Scheme 5, compound of Formula Int-1 is activated and reacted with an amine to provide Int-2 first, and then followed with the coupling reaction, to provide compound of Formula 1-4.

(192) ##STR00162##

(193) Scheme 6 illustrates a method for preparing compounds of Formula 1-5.

(194) Bromine of Int-1 was displaced with methoxy group to afford Int-2, and then Int-2 was halogenated with NBS or NIS to offer Int-3. From Int-3, after the substitution, coupling and deprotection compounds of formula 1-5 (R.sub.3H) were synthesized. The compound of Formula 1-5 wherein R 3H may be subjected to an alkylation reaction to provide another series compound of Formula 1-5.

EXPERIMENTAL PROCEDURES AND EXAMPLES

(195) Experiments were generally carried out under inert atmosphere (nitrogen or argon), particularly in cases where oxygen- or moisture-sensitive reagents or intermediates were employed. Commercial solvents and reagents were generally used without further purification, including anhydrous solvents where appropriate. Products were generally dried under vacuum before being carried on to further reactions or submitted for biological testing. Mass spectrometry data is reported from liquid chromatography-mass spectrometry (LCMS) instrumentation. Mass spectra, MS (m/z), were recorded using either electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI). Where relevant and unless otherwise stated the m/z data provided are for isotopes 19F, 35Cl, 79Br and 1271. Chemical shifts for nuclear magnetic resonance (NMR) data are expressed in parts per million (ppm, 6) referenced to residual peaks from the deuterated solvents employed, using conventional abbreviations for designation of major peaks: e.g. s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; br, broad. The following abbreviations have been used for common solvents: CDCl.sub.3, deuterochloroform; d6-DMSO, derterodimethylsulphoxide; and CD.sub.3OD, deuteromethanol.

(196) In general, reactions were followed by thin layer chromatography (TLC) and/or liquid chromatography-mass spectrometry (LCMS) and subjected to work-up when appropriate. Purification was carried out by chromatographic and/or HPLC.

(197) Unless noted otherwise, all reactants were obtained commercially.

(257) IC.sub.50 values were determined at room temperature in 384-well black polystyrene plate, using a final reaction volume of 15 l and the following assay buffer conditions: 60 mM Hepes (pH=7.2), 75 mM NaCl, 75 mM KCl, and 1 mM EDTA, 0.05% P-20, 5 mM dithiothreitol (DTT). Full length SHP2 enzyme (diluted to 0.1 nM in reaction buffer) were co-incubated with 1 uM IRS-1 peptide and 0.01 nM to 10 M compounds of the disclosure for 60 min. The surrogate substrate DiFMUP (5 L, 100 LIM) was added, and incubated at rt for 60 min. The reaction was then quenched by the addition of 5 L of a 40 M solution of bpV(Phen). The fluorescence signal was monitored using a microplate reader (Envision, Perkin-Elmer) using excitation and emission wavelengths of 360 nm and 450 nm, respectively. The inhibitor dose-response curves were analyzed using normalized IC.sub.50 regression curve fitting with control-based normalization. The inhibitory activity results of the compounds of the disclosure is shown in Table 2.

KYSE-520 Xenograft Model

(263) KYSE-520 cells were expanded in culture, harvested and injected subcutaneously into 6-8 weeks old female BALB/c nude mice (510.sup.6 cell/each mouse, supplemented with Matrigel (1:1) for tumor development, n=9 per group). Subsequent administration of a compound by oral gavage started when the mean tumor size reached approximately 150-200 mm.sup.3. During the treatment (once a day for 4 weeks), the tumor volumes were measured using a caliper. Statistical analysis of difference in tumor volume among the groups were evaluated using a one-way ANOVA. Vehicle alone was the negative control.

(264) Many of the compounds described herein is very potent and selective, with enzymatic IC.sub.50 less than 10 nM. The compounds tested also displayed superior anti-tumor activities in the in vivo animal models. In some embodiments, the dose amount per day falls within the range of 3-100 mg/kg to achieve the tumor regression or >80% tumor growth inhibition.
