실험 절차

20 μL of a IM trimethylphosphine/tetrahydrofuran solution was added to 6 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 dissolved in a mixture of 0.15 mL of tetrahydrofuran and 0.02 mL of water at room temperature, and the mixture was stirred for 13 hours. After the solvent was distilled under reduced pressure, the residue was purified by reverse phase column chromatography (Wako gel 50C18 (made by Wako Pure Chemical Industries Ltd.), eluent: water to a 50% aqueous solution of acetonitrile), and the obtained solids were further washed with tetrahydrofuran, thereby yielding 2 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-aminoethyl) ester.
