実験手順

To tert-butyl (6R,7R)-7-(4-chloro-3-fluorophenyl)-6-{[(ethoxyacetyl)amino]methyl}-1,4-oxazepane-4-carboxylate (125 mg) was added 4.0 M hydrogen chloride-ethyl acetate solution (2.11 ml), and the mixture was stirred at room temperature for 1 hr. The residue obtained by concentration under reduced pressure was recrystallized from ethanol-diisopropyl ether to give the title compound (92.0 mg).
