A mixture of 2-butyl-3-[4-[4-ethoxycarbonyl-2-(1-trityl-1H-tetrazol-5-yl)-1-pyrrolyl]benzyl]-7-methyl-3H-imidazo[4,5-b]pyridine (115 mg), conc. hydrochloric acid (0.25 ml) and methanol (20 ml) was stirred for 2 hours and concentrated under reduced pressure. The residue was purified by preparative thin layer chromatography to give 2-butyl-3-[4-[4-ethoxycarbonyl-2-(1H-tetrazol-5-yl)-1-pyrrolyl]benzyl]-7-methyl-3H-imidazo[4,5-b]pyridine [53 mg) as a colorless viscous oil.
