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 (155.4 mg, 0.26 mmol) and (2S,4S)-4-mercapto-N-(p-nitrobenzyloxycarbonyl)-2-[3-[(p-nitrobenzyloxycarbonyl)amino]-2-pyrrolidon-4-yl]pyrrolidine (110 mg, 0.197 mmol, compound of Reference Example 20-6) to obtain p-nitrobenzyl (1R,5S,6S)-6-[(R)-1-hydroxyethyl]-1-methyl-2-[(2S,4S)-N-(p-nitrobenzyloxycarbonyl)-2-[3-[(p-nitrobenzyloxycarbonyl)amino]-2-pyrrolidon-4-yl]pyrrolidin-4-ylthio]-1-carbapen-2-em-3-carboxylate (87 mg, yield: 48.9%).
