実験手順

To a solution of tert-butyl (6R,7R)-6-(aminomethyl)-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (150 mg) in THF (2 mL) were added triethylamine (60.7 mg) and methanesulfonyl chloride (68.7 mg) under ice-cooling, and the mixture was stirred for 1 hr. The solvent was evaporated under reduced pressure, distilled 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 (hexane/ethyl acetate) to give the title compound (161 mg).
