Reaction Steps

A mixture of 7-methyl-2-propyl-3-[4-[2-(1H-tetrazol-5-yl)-4-vinyl-1-pyrrolyl]benzyl]-3H-imidazo[4,5-b]pyridine (40 mg), 10% palladium on carbon (10 mg) and methanol (5 ml) was stirred at room temperature for 4 hours under hydrogen atmosphere (3 atm). After filtration, the filtrate was evaporated in vacuo. The residue was purified by preparative thin layer chromatography (dichloromethane:methanol=5:1) to give 3-[4-[4-ethyl-2-(1H-tetrazol-5-yl)-1-pyrrolyl]benzyl]-7-methyl-2-propyl-3H-imidazo[4,5-b]pyridine (20 ml).
