実験手順

Acetyl chloride (23 mg) was added to a solution of tert-butyl (6SR,7SR)-6-amino-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (90 mg) and triethylamine (33 mg) in THF (5 ml), and the mixture was stirred at room temperature for 1 hr. Water was added to the reaction mixture, 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 (93 mg).
