Versuchsvorschrift

To a solution of tert-butyl (6R,7R)-6-(aminomethyl)-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (171 mg) in dimethoxyethane (3 mL) was added 1 N aqueous sodium hydroxide solution (0.72 ml), and the mixture was stirred overnight. The solvent was evaporated under reduced pressure. Water was added to the residue, and the mixture was extracted twice with ethyl acetate. The combined organic layers were washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/hexane) to give the title compound (157 mg).
