A procedure similar to that described in Example 101 was repeated, but using 4-nitrobenzyl (1R,5S,6S)-2-(diphenylphosphoryloxy)-6-[(1R)-1-hydroxyethyl]-1-methyl -1-carbapen-2-em-3-carboxylate (prepared as described in Preparation 123) and (2S,4S)-4-mercapto-1-(4-nitrobenzyl -oxycarbonyl)-2-[4-(4-nitrobenzyloxycarbonylamidino)homopiperazin -1-ylcarbonyl]pyrrolidine (prepared as described in Preparation 94) as starting materials, in relative proportions similar to those used in that Example, to obtain the title compound.
