Methyl 3-(2-chloro-4-(E)-(2-phenylethenyl)benzyl)-2-methyl-3H-imidazo[4,5-b]pyridine-5-carboxylate (2.37 g) was dissolved in methanol/chloroform=1/4 (24 ml), and platinum(IV) oxide (169 mg) was added. The mixture was stirred under a hydrogen atmosphere at normal pressure for 4 hours. Platinum(IV) oxide (169 mg) was added, and the mixture was further stirred under a hydrogen atmosphere at normal pressure for 6 hr. The reaction mixture was filtered through Celite and the filtrate was concentrated to dryness under reduced pressure. The obtained residue was subjected to silica gel column chromatography (eluent: ethyl acetate/chloroform=1/3). The fraction containing the objective compound was concentrated under reduced pressure to give the objective compound (1.92 g) as a white powder.
