Reaction Steps

The same procedure as in Example 1-1 was carried out by using p-nitrobenzyl (5R,6S)-2-diphenoxyphosphoryloxy-6-8 (R)-1-hydroxyethyl]-1-carbapen-2-em-3-carboxylate (235 mg, 0.40 mmol) and (2S,4S)-4-mercapto-2-(N-methyl-2-azetidinon-4-yl)-N-(p-nitrobenzyloxycarbonyl)pyrrolidine (149 mg, 0.41 mmol, compound of Reference Example 7) to obtain p-nitrobenzyl (5R,6S)-6-[(R)-1-hydroxyethyl]-2-[(2S,4S)-2-(N-methyl-2-azetidinon-4-yl)-N-(p-nitrobenzyloxycarbonyl)pyrrolidin-4-ylthio]-1-carbapen-2-em-3-carboxylate (265 mg, yield: 94.5%).
