Procedure

To a solution of tert-butyl (6S,7R)-7-(4-chloro-3-fluorophenyl)-6-(hydroxymethyl)-1,4-oxazepane-4-carboxylate (4.50 g) in THF (41.7 mL) were added triethylamine (3.49 mL) and methanesulfonyl chloride (1.94 mL) under ice-cooling, and the mixture was stirred for 3 hr. To the reaction mixture was added distilled water, and the mixture was extracted with ethyl acetate. The extract was washed with distilled water and brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (6.01 g).
