Reaction Steps

To a solution of tert-butyl (6R,7R)-7-(4-chloro-3-fluorophenyl)-6-{[(methoxyacetyl)amino]methyl}-1,4-oxazepane-4-carboxylate (1.11 g) in ethanol (13 mL) was added 14.0 M hydrogen chloride-ethanol solution (12.0 ml), and the mixture was stirred at room temperature for 1 hr. The crystals obtained by concentration under reduced pressure were recrystallized from ethanol-hexane to give the title compound (715 mg).
