Versuchsvorschrift

To a mixture of 6-cyano-2-(2-ethylsulfanylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (0.40 g) and chloroform (5 ml), 70% of 3-chloroperbenzoic acid (0.35 g) was added under ice-cooling, and stirred at room temperature for 2 hours. To the reaction mixture, saturated aqueous sodium hydrogen carbonate solution was added, and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure to give 0.40 g of 6-cyano-2-(2-ethylsulfinylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (hereinafter referred to as Present Compound 49).
