Procedure

A mixture of the compound obtained in Example 4 (142 mg), 1N aqueous sodium hydroxide solution (0.60 ml) and methanol (5 ml) is stirred at room temperature overnight, and evaporated under reduced pressure to remove the solvent. The resulting residue is purified by column chromatography of nonionic adsorbing resin (tradename; HP-20, manufactured by Mitsubishi Kasei Corporation, Japan), and lyophilized to give 2-n-butyl-5-acetyl-3-[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl-4,5,6,7-tetrahydroimidazo[4,5-c]pyridine-4-carboxylic acid disodium salt (100 mg).
