実験手順
To a solution of tert-butyl (6R,7R)-6-(aminomethyl)-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (100 mg) in acetonitrile (2 mL) was added N-(tert-butoxycarbonyl)-N-[4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl]azanide (181 mg) prepared by the method described in Organic Letters, 2001, 3 (14), 2241-2243, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was concentrated under reduced pressure, distilled water was added to the residue, and the mixture was extracted twice with ethyl acetate. The combined organic layers were washed with 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 (172 mg).
