Procedure
A mixture of (2S,4R)-2-[(Z)-5-bromo-1-pentenyl]-1-(4-chlorophenylsulfonyl)-4-(4-chlorophenylsulfonylamino)pyrrolidine (200 mg) and triethyl phosphite (5.0 ml) was refluxed for 3 hours and evaporated in vacuo to give an oil. The oil was chromatographed on silica gel column with chloroform as an eluent to give (2S,4R)-1-(4-chlorophenylsulfonyl)-4-(4-chlorophenylsulfonylamino)-2-[(Z)-5-diethoxyphosphoryl-1-pentenyl]pyrrolidine (164 mg) as an oil.
