Procedure

436 mg of 3-chloroperoxybenzoic acid (purity of 65% or more) was added to a mixture of 236 mg of 2-(2-ethylsulfanyl-4-trifluoromethylphenyl)-6-trifluoromethyl-imidazo[1,2-a]pyridine and 5 ml of chloroform under ice cooling, and the mixture was stirred at room temperature for 4 hours. A 10% aqueous sodium thiosulfate solution was poured to the reaction mixture, and the mixture was extracted with chloroform. The organic layer was washed with a saturated aqueous sodium bicarbonate solution and dried over anhydrous magnesium sulfate, then concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 122 mg of 2-(2-ethylsulfonyl-4-trifluoromethylphenyl)-6-trifluoromethyl-imidazo[1,2-a]pyridine (hereinafter, referred to as Compound of Present Invention 7).
