To a solution of tert-butyl (6SR,7SR)-7-(aminomethyl)-6-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (200 mg) in DMF (5 mL) were added WSC (100 mg), HOBt (90 mg), triethylamine (0.10 mL) and 2-(1H-1,2,4-triazol-1-yl)acetic acid (74 mg), and the mixture was stirred at room temperature overnight. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate, and the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (190 mg).
