Reaction Steps

A mixture of 200 mg of 2-bromo-6-trifluoromethyl-imidazo[1,2-a]pyridine, 332 mg of 2-ethylsulfanyl-4-trifluoromethylphenylboronic acid pinacol ester, 21 mg of tris(dibenzylideneacetone) dipalladium(0), 85 mg of tricyclohexylphosphine (18% toluene solution), 480 mg of tripotassium phosphate, 1.5 ml of 1,4-dioxane and 0.5 ml of water was stirred at 100° C. for 4 hours. Water was poured to the cooled reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 236 mg of 2-(2-ethylsulfanyl-4-trifluoromethylphenyl)-6-trifluoromethyl-imidazo[1,2-a]pyridine (hereinafter, referred to as Compound of Present Invention 6).
