실험 절차

A solution of (2S,4R)-1-t-butoxycarbonyl-2-[{Z)-5-carboxy-1-pentenyl]-4-(4-chlorophenylsulfonylamino)pyrrolidine (2.90 g) in methanol (50 ml) saturated with hydrogen chloride was stirred at room temperature overnight and the solvent was evaporated in vacuo. The residue was dissolved in chloroform (50 ml) and the solution was washed successively with saturated aqueous sodium bicarbonate and brine. The organic layer was dried over magnesium sulfate and the solvent was evaporated in vacuo to give (2S,4R)-4-(4-chlorophenylsulfonylamino)-2-[(Z)-5-methoxycarbonyl-1-pentenyl]pyrrolidine (2.28 g) as a pale brown oil.
