Procedure

2.26 g of (2S,4S)-4-(4-methoxybenzylthio)-2-[(3S)-3-methylpiperazin-1-ylcarbonyl]-1-(4-nitrobenzyloxycarbonyl)pyrrolidine hydrochloride [prepared as described in step (i) above] were mixed with 1.14 g of N-(4-nitrobenzyloxycarbonyl)acetamidine and 45 ml of acetonitrile, and the mixture was heated under reflux for 16 hours. At the end of this time, the reaction mixture was worked up and purified by the same procedure as described in Preparation 1(ii), to give 922 mg of the title compound, as a powder.
