Reaction Steps

160 mg of 4-nitrobenzyl (1R, 5S, 6S)-2-{(2S, 4S)-2-[3-(4-nitrobenzyloxycarbonyl)-4-(4-nitrobenzyloxycarbonyl)-1-piperazinylcarbonyl]-1-(4-nitrobenzyloxycarbonyl)pyrrolidin-4-ylthio}-6-[(1R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate [prepared as described in step (a) above] were dissolved in 3 ml of a 1:1 by volume mixture of tetrahydrofuran and water, and the mixture was hydrogenated by bubbling hydrogen through it at room temperature for 2 hours in the presence of 160 ml of 10% w/w palladium-on-charcoal. At the end of this time, the reaction mixture was worked up and purified by the same procedure as described in Example 7(b), to give 35 ml of the title compound, as a powder.
