[0378] ##STR00388##

Step 4.1: 3,2,3-Trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-ol

[0379] ##STR00389##

[0380] A mixture of 6-bromo-2-fluoro-3-trifluoromethoxyphenol (2, CAS 1805580-O1-1) (33.0 g, 0.12 mol), potassium carbonate (25.0 g, 0.18 mol), tris(dibenzylideneacetone)-dipalladium(0) (600 mg, 0.6 mmol) and CataCXium A (700 mg, 1.9 mmol) in THF (250 mL) and distilled water (75 mL) is heated to reflux under nitrogen atmosphere, followed by dropwise addition of a solution of 2,3-difluoro-4-(4-propylcyclohexyl)-phenylboronic acid (1, CAS 183438-45-1) (34.4 g, 0.12 mol) in THF (100 mL). The reaction mixture is heated at reflux temperature overnight. Then it is cooled to room temperature and diluted with MTB ether and distilled water. Throughout this application, unless explicitly stated otherwise, room temperature and ambient temperature are used synonymously and signify a temperature of about 20? C., typically (20?1?) C. The aqueous phase is separated and extracted with MTB ether. The combined organic phases are washed with distilled water and brine, dried (sodium sulphate) and concentrated in vacuo. The residue is purified by silica gel chromatography (solvent 1-chlorobutane/heptane 1:1). 3,2,3-Trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-ol (3) is isolated as a yellow solid.

Step 4.2: Trifluoromethanesulfonic acid 3,2,3-trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-yl ester

[0381] ##STR00390##

[0382] Trifluoromethanesulfonic anhydride (6.0 mL, 36.4 mmol) is slowly added to a solution of 3,2,3-trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-ol (3) (12.6 g, 29.0 mmol), TEA (6.3 mL, 45.4 mmol) and DMAP (110 mg, 0.9 mmol) in dichloromethane (100 mL) at 5? C. under nitrogen atmosphere. The solution is stirred at room temperature overnight. The reaction mixture is purified by silica gel chromatography (solvent dichlormethane) to give trifluoromethanesulfonic acid 3,2,3-trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-yl ester (4) as a yellow oil.

Step 4.3: 4,6-Difluoro-3-(4-propyl-cyclohexyl)-7-trifluoromethoxy-dibenzothiophene

[0383] ##STR00391##

[0384] This reaction is performed as a one-pot reaction. In the first step, a solution of trifluoromethanesulfonic acid 3,2,3-trifluoro-4-(4-propyl-cyclohexyl)-4-trifluoromethoxy-biphenyl-2-yl ester (4) (16.3 g, 28.1 mmol) and ethyl 3-mercaptopropionate (5.0 mL, 37.9 mmol) in toluene (150 mL) is quickly heated under nitrogen atmosphere to 80? C. Potassium carbonate (10 g, 72.4 mmol), tris(dibenzylideneacetone)dipalladium(0) (1.4 g, 1.5 mmol) and (oxydi-2,1-phenylene)bis(diphenylphosphine) (1.6 g, 2.9 mmol) are quickly added to the solution, and the reaction mixture is heated at reflux temperature overnight. Then it is allowed to cool to room temperature. In the second step, a solution of potassium tert-butylate (3.5 g, 31.2 mmol) in THF (50 mL) is added to the reaction mixture containing intermediate (5) in situ. The reaction mixture is heated at reflux temperature overnight, followed by addition of a second portion of a solution of potassium tert-butylate (3.5 g, 31.2 mmol) in THF (50 mL). The reaction mixture is heated at reflux temperature overnight. Then it is cooled to room temperature, quenched with distilled water and hydrochloric acid (25%) at 0? C. and diluted with MTB ether. The aqueous phase is separated and extracted with MTB ether. The combined organic phases are washed with distilled water and brine, dried (sodium sulphate) and concentrated in vacuo. The residue is purified by silica gel chromatography (solvent heptane) to give 4,6-difluoro-3-(4-propyl-cyclohexyl)-7-trifluoromethoxy-dibenzothiophene (6) as colorless crystals.

[0385] Compound (6) has the following phase characteristics: [0386] K 108? C. SmA 141? C. N 169? C. I

Synthesis Example 4a (CB(S)-3-OT)

[0387] Alternatively, 4,6-Difluoro-3-(4-propyl-cyclohexyl)-7-trifluoromethoxy-dibenzothiophene is obtained by hydrogenation of 4,6-Difluoro-3-(4-propyl-cyclohex-1-enyl)-7-trifluoromethoxy-dibenzothiophene:
