Procedure
To a solution of tert-butyl (6S,7R)-7-(3,4-dichlorophenyl)-6-{[(methylsulfonyl)amino]methyl}-1,4-oxazepane-4-carboxylate (162 mg) in ethanol (0.5 mL) was added 4.0 M hydrogen chloride-ethyl acetate solution (3 mL), and the mixture was stirred at room temperature for 2 hr. The solvent was evaporated under reduced pressure. The obtained crystals were recrystallized from ethanol-water to give the title compound (109 mg) as colorless crystals.
