実験手順

To a solution of tert-butyl (6R,7R)-6-(aminomethyl)-7-(4-chloro-3-fluorophenyl)-1,4-oxazepane-4-carboxylate (1.30 g) in THF (18 mL) were added triethylamine (0.757 ml) and methoxyacetyl chloride (472 mg), and the mixture was stirred at room temperature for 4 hr. To the reaction mixture was added distilled water, and the mixture was extracted with ethyl acetate. The diluted solution was washed with distilled water and brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (1.11 g).
