Reaction Steps

A mixture of (2S,4R)-2-[(E and Z)-5-carboxy-1-pentenyl]-4-phenylsulfonylaminopyrrolidine (169 mg), triethylamine (0.070 ml) and phenyl isocyanate (0.060 ml) in methanol (5 ml) was stirred at room temperature overnight and water was added to the solution. The solution was extracted with chloroform and organic phase was washed with brine. After the solution was dried over magnesium sulfate, the solvent was evaporated in vacuo and the residue was chromatographed on a silica gel column with a mixture of chloroform and methanol (40:1) as an eluent to give (2S,4R)-2-[(E and Z)-5-carboxy-1-pentenyl]-1-phenylcarbamoyl-4-phenylsulfonylaminopyrrolidine (51 mg) as an oil.
