Versuchsvorschrift
To a solution of tert-butyl (6S,7R)-7-(3,4-dichlorophenyl)-6-{[(methylsulfonyl)oxy]methyl}-1,4-oxazepane-4-carboxylate (1.43 g) in DMF (15 mL) was added sodium azide (322 mg), and the mixture was stirred at 70° C. overnight. The solvent was evaporated under reduced pressure, distilled water was added to the reaction mixture, and the mixture was extracted twice with ethyl acetate. The combined organic layers were washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (1.23 g).
