Participants

Reaction Steps

Following a procedure similar to that described in Example 1, but using 181 mg of 4-nitrobenzyl (1R, 5R, 6S)-6-[(1R)-1-hydroxyethyl]-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 220 mg of (2S, 4S)-4-mercapto-2-[4-(N-4-nitrobenzyloxycarbonylacetimidoyl)piperazin-1-ylcarbonyl]-1-methylpyrrolidine (prepared as described in Preparation 44), 20 mg of the title compound were obtained, as a powder.
