実験手順

To a mixture of 2-(2-ethylsulfanylphenyl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (0.25 g) and chloroform (3 ml), 3-chloroperbenzoic acid (purity: not less than 65%, 0.43 g) was added under ice-cooling, and then heated to room temperature, and stirred for 1 hour. To the reaction mixture, chloroform was added under ice-cooling, and then saturated aqueous sodium, thiosulfate solution was poured, and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium hydrogen carbonate solution, then saturated trine, dried over sodium sulfate, and concentrated under reduced pressure. The obtained crystal was washed with hexane, then methyl-tert-butyl ether to give 0.27 g of 2-(2-ethylsulfonylphenyl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (hereinafter referred to as Present Compound 6).
