Versuchsvorschrift

4.37 ml of a 4N solution of hydrogen chloride in ethyl acetate were added, whilst ice-cooling, to a solution of 3.00 g of (2S,4S)-4-(4-methoxybenzylthio)-2-[(3S)-3-aminopyrrolidin-1-ylcarbonyl]-1-(4-nitrobenzyloxycarbonyl)pyrrolidine [prepared as described in step (i) above] in 30 ml of ethyl acetate, and the resulting mixture was stirred at the same temperature for 30 minutes. At the end of this time, it was diluted with ethyl acetate, and the powder which precipitated was collected by filtration and dried, to give 3.20 g of the title compound, as a powder.
