Reaction Steps

The same procedure as in Example 1-1 was carried out by using p-nitrobenzyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen- 2-em-3-carboxylate (10.61 g, 17 mmol) and (2S,4S)-4-mercapto-N-(p-nitrobenzyloxycarbonyl)-2-(2-pyrrolidon-4-yl)pyrrolidine diastereomer B (5.92 g, 16.2 mmol, compound of Reference Example 19-4) to obtain p-nitrobenzyl (1R,5S,6S)-6-[(R)-1-hydroxyethyl]-1-methyl-2-[(2S,4S)-N-(p-nitrobenzyloxycarbonyl)-2-(2-pyrrolidon-4-yl)pyrrolidin-4-ylthio]-1-carbapen-2-em-3-carboxylate diastereomer B (9.9 g, yield: 83.7%).
