Versuchsvorschrift

6 mg of sodium azide was added to 18 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid 6-(2-iodoethyl)ester dissolved in a mixture of 0.2 mL of N,N-dimethylformamide and 0.02 mL of water at room temperature, and the mixture was stirred for 12 hours at 60° C. After standing to cool, the solvent was distilled under reduced pressure, and the residue was purified by reverse phase column chromatography (Wako gel 50C18, eluent: water to a 70% aqueous solution of acetonitrile), thereby yielding 7 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid 6-(2-azidoethyl)ester
