In 15 ml of 1N sodium hydroxide solution is dissolved 0.5 g of 3(S)-[7-amino-1(S)-ethoxycarbonylheptyl]amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine-5-acetic acid dihydrochloride obtained in Example 68, and the solution is allowed to stand at room temperature for 30 minutes. Acetic acid (3.5 ml) is added to the solution and the mixture is purified by Amberlite XAD-2 column chromatography (methanol:water=1:2). The eluate is concentrated under reduced pressure and lyophilized to give 0.31 g of 3(S)-[7-amino-1(S)-carboxyheptyl]amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine-5-acetic acid as a colorless powder.
