Participants

Reaction Steps

To tert-butyl (6RS,7RS)-7-(3,4-dichlorophenyl)-6-(hydroxymethyl)-1,4-oxazepane-4-carboxylate (896 mg) were added triethylamine (0.50 mL) and methanesulfonyl chloride (0.26 mL) under ice-cooling, and the mixture was stirred for 1 hr. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with ethyl acetate. The diluted solution was washed with 1 N hydrochloric acid, distilled water and brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (1.07 g).
