Reaction Steps
To a solution of tert-butyl (6RS,7SR)-7-(3,4-dichlorophenyl)-6-{[(methylsulfonyl)oxy]methyl}-1,4-oxazepane-4-carboxylate (1.26 g) in DMF (10 mL) was added sodium cyanide (204 mg), and the mixture was stirred at 80° C. for 18 hr. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with ethyl acetate. The diluted solution was washed with distilled water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (990 mg).
