Procedure

To a mixture of 2-(3-chloro-5-trifluoromethylpyridin-2-yl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (0.71 g) and DMF (4 ml) was added sodium ethanethiolate (0.24 g) while ice-cooling, and the mixture was stirred at room temperature for 1 hour. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give 2-(3-ethylsulfanyl-5-trifluoromethylpyridin-2-yl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (0.76 g), which is hereinafter referred to as “the present compound 4”.
