To a solution of tert-butyl (6R,7S)-6-amino-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (300 mg) in acetonitrile (5 mL) was added N-(tert-butoxycarbonyl)-N-[4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl]azanide (375 mg) prepared by the method described in Organic Letters, 3 (14), 2241-2243 (2001), and the mixture was stirred at room temperature overnight. The reaction mixture 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, and the residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (200 mg).
