Reaction Steps

The same procedure as in Example 1-1 was conducted by using p-nitrobenzyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate (230 mg, 0.41 mmol) and (2S,4S)-4-mercapto-N-(p-nitrobenzyloxycarbonyl)-2-(2-pyrrolidon-4-yl)pyrrolidine (140 mg, 0.38 mmol, Compound of Reference Example 1-9) 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 (223 mg, yield: 80.6%).
