Procedure

A mixture of 9-[4-(benzyloxy)phenyl]-9H-imidazo[1′,2′:1,2]imidazo[4,5-b]pyridine (2.48 g), 10% palladium on carbon (containing water (50%), 2.48 g), THF (50 mL) and methanol (50 ml) was stirred under a hydrogen atmosphere at room temperature for 1 hr. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/THF) and recrystallized from ethanol to give the title compound (1.38 g).
