Reaction Steps

To a solution of tert-butyl (6S,7R)-6-(3,4-dichlorophenyl)-7-(hydroxymethyl)-1,4-oxazepane-4-carboxylate (3.0 g) in acetonitrile (20 mL) was added Dess-Martin reagent (5.1 g), and the mixture was stirred at 10° C. for 4 hr. To the reaction mixture were added saturated aqueous sodium hydrogen carbonate and aqueous sodium sulfite solution, and the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (1.3 g).
