7.3 μL of pyridine and 14 mg of 3,4-dichlorobenzoyl chloride were added to 17 mg of (1R,2R,3R,5R,6R)-3-amino-2-t-butoxycarbonylamino-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid diethyl ester dissolved in 0.17 mL of chloroform, and the mixture was stirred for 3 hours at room temperature. The reaction solution was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel: Wako gel C200, eluent: chloroform-ethanol=100:1), thereby yielding 21 mg of (1R,2R,3R,5R,6R)-2-t-butoxycarbonylamino-3-(3,4-dichlorobenzoylamino)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid diethyl ester
