実験手順

To a solution of tert-butyl (6R,7R)-7-(4-chloro-3-fluorophenyl)-6-{[3-(methoxycarbonyl)-2-oxopyridin-1(2H)-yl]methyl}-1,4-oxazepane-4-carboxylate (155.7 mg) in ethanol (1.5 mL) was added hydrazine monohydrate (79 mg) at room temperature, and the mixture was heated under reflux for 2 days. The reaction mixture was allowed to cool to room temperature, and poured into water, and the mixture was partitioned with ethyl acetate. The organic layer was washed with brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (138 mg).
