Procedure
The title compound was prepared by a similar method to Example 1 from L-proline benzyl ester hydrochloride and 4-fluorobenzenesulphonyl chloride. The crude product was purified by column chromatography on silica gel eluting with dichloromethane to afford benzyl (2S)-1-[(4-fluorophenyl)sulfonyl]-2-pyrrolidinecarboxylate as a clear oil.
