実験手順

Following a procedure similar to that described in Example 6, but using 459 mg of 4-nitrobenzyl (5R, 6S)-6-[(1R)-1-hydroxyethyl]-2-oxo-1-carbapenam-3-carboxylate and 580 mg of the crude (2S, 4S)-2-(N,N-dimethylcarbamoyl)-1-ethyl-1-methyl-4-mercaptopyrrolidinium salt [prepared as described in Example 9-(2)], 55 mg of the title compound were obtained.
