Versuchsvorschrift

To a solution of tert-butyl (6R,7R)-7-(aminomethyl)-6-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (140 mg) and triethylamine (0.156 mL) in THF (3.0 mL) was added acetoxyacetyl chloride (81 mg), and the mixture was stirred at room temperature overnight. To the reaction solution was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (168 mg).
