Reaction Steps

(E)-5-(Benzenesulfonylcarbamoyl)-3-(2-chloro-4-(2-phenylethenyl)-benzyl)-2-methyl-3H-imidazo[4,5-b]pyridine (42 mg) was suspended in a mixed solvent of chloroform (4 ml), 1,4-dioxane (2 ml) and methanol (2 ml), and platinum oxide (2 mg) was added. The mixture was stirred at room temperature for 6.5 hr under a hydrogen atmosphere at 1 atm. The reaction mixture was filtrated and the solvent was evaporated. The resultant mixture was purified by silica gel column chromatography (chloroform/methanol=20/1) and crystallized from ethyl acetate/hexane to give 5-(benzenesulfonylcarbamoyl)-3-(2-chloro-4-(2-phenylethyl)benzyl)-2-methyl-3H-imidazo[4,5-b]pyridine (18 mg) as a white powder.
