실험 절차

0.36 mL of trifluoromethane sulfonic acid anhydride dissolved in 1.2 mL of dichloromethane was added dropwise to 364 mg of (1R,2R,3S,5R,6R)-2-azido-6-fluoro-3-hydroxy-bicyclo[3.1.0]hexane-2,6-dicarboxylic acid diethyl ester dissolved in 6.1 mL of dichloromethane and 0.21 mL of pyridine at −77° C. to −69° C., under a nitrogen atmosphere. The mixture was stirred for 30 minutes at −77° C., and further stirred for 30 minutes at ice-cooling. 30 mL of diethyl ether was added thereto, and after the solids were filtered off, the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel: Wako gel C200, eluent: hexane-ethyl acetate=5:1), thereby yielding 487 mg of (1R,2R,3S,5R,6R)-2-azido-6-fluoro-3-trifluoromethanesulfonyloxy-bicyclo[3.1.0]hexane-2,6-dicarboxylic acid diethyl ester.
