실험 절차

19 μL of thionyl chloride was added to 26 mg of (1R,2S,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzylsulfanyl)-6-fluoro-bicyclo[3.1.0]hexane-2,6-dicarboxylic acid suspended in 0.3 mL of benzyl alcohol at ice-cooling, and then the mixture was stirred for 3.5 hours at 50° C. After standing to cool, the reaction solution was concentrated under reduced pressure, and the residue was purified by reverse phase column chromatography (Wako gel 50C18 (Wako Pharmaceutical Industries Ltd.), eluent: water to an aqueous 70% solution of acetonitrile), thereby yielding 5 mg of (1R,2S,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzylsulfanyl)-6-fluoro-bicyclo[3.1.0]hexane-2,6-dicarboxylic acid 6-benzyl ester. 2.19-2.43 (3H, m), 2.47-2.63 (1H, m), 2.96-3.12 (1H, m), 3.75 (1H, d, J=13.2 Hz), 3.81 (1H, d, J=13.2 Hz), 5.22 (2H, s), 7.23-7.54 (8H, m)
