Procedure:
A solution of 2-chloro-5-fluorotoluene (5.0 g) in acetic anhydride (40 ml) was treated dropwise with concentrated sulfuric acid (40 ml) with cooling on ice. Subsequently, a solution of chromic anhydride (9.3 g) in acetic anhydride (40 ml) was added dropwise over a period of 2 hours. At the same temperature, the mixture was stirred for 1 hour, and added to an ice-water. The mixture was extracted with diethyl ether and the organic layer was washed successively with aqueous sodium carbonate, water and saturated brine, and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was dissolved in tetrahydrofuran (10 ml), combined with water (4 ml) and concentrated sulfuric acid (4 ml), and heated with stirring at 100° C. for 30 minutes. After allowed to stand to cool, the reaction mixture was extracted with ethyl acetate, and the organic layer was washed successively with aqueous sodium carbonate, water and saturated brine, and dried over magnesium sulfate. The solvent was distilled off and the residue was subjected to a column chromatography on a silica gel to obtain 2-chloro-5-fluorobenzaldehyde (1.6 g).

Procedure:
To a solution of 46 mg (0.48 mmol) 3-hydroxypyridine in 3 mL N,N-dimethylformamide were added 21 mg (0.48 mmol, 55% dispersion in mineral oil) sodium hydride. The reaction mixture was stirred for 10 min. at room temperature. To this suspension 0.2 g (0.44 mmol) 1-(2-bromo-1-cyclohexyl-ethyl)-2-(4-chloro-phenyl)-5,6-difluoro-1H-benzoimidazole (Ex. 34, int.) were added and the reaction mixture stirred for 4 days at room temperature. The reaction mixture was poured on 30 mL 1N hydrochloric acid and 30 mL ethyl acetate and the phases separated. The aqueous layer was extracted with 30 mL ethyl acetate. The combined organic layers were washed twice with 30 mL water and once with 30 mL brine, dried over magnesium sulfate, filtered and evaporated. The residue was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:ethyl acetate (100:0 to 60:40) to give the desired compound as white solid (65%). MS (Turbo Spray): m/z=468.2 [M+H].
