Procedure

0.16 g of m-chloroperbenzoic acid was added to a solution of 0.38 g of 2-[{3-methyl-4-(2-pyridylmethoxyethoxy)pyridine-2-yl}methylthio]-1H-benzimidazole in 20 ml of dichloromethane at -60° C. in a nitrogen atmosphere to obtain a mixture. This mixture was stirred for 0.5 hour. After the completion of the reaction, 0.16 g of triethylamine was added to the reaction mixture. The obtained mixture was heated to -10° C., followed by the addition of 30 ml of a saturated aqueous solution of sodium hydrogencarbonate. The obtained mixture was stirred at a room temperature for 0.5 hour and extracted with 50 ml of dichloromethane thrice. The extract was dried over magnesium sulfate and filtered. The filtrate was concentrated and dried in a vacuum to obtain a crude product. This crude product was crystallized from dichloromethane/diethyl ether to obtain 0.31 g of 2-[{3-methyl-4-(2-pyridylmethoxyethoxy)pyridine-2-yl}methylsulfinyl]-1H-benzimidazole as a white crystal.
