Procedure
In 10 ml of 5N hydrogen chloride-ethyl acetate solution is dissolved 1.1 g of tert-butyl 3(S)-[7-tert-butoxycarbonylamino-1(S)-ethoxycarbonylheptyl]amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine-5-acetate obtained in Example 67 and the solution is allowed to stand at room temperature for 3 hours. Petroleum ether (100 ml) is added to the solution and the deposited precipitate is dried under reduced pressure to give 0.9 g of 3(S)-[7-amino-1(S)-ethoxycarbonylheptyl]amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine-5-acetic acid dihydrochloride as a colorless powder.
