Procedure

The same procedure as in Example 8-1 was carried out by using allyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate (331 mg, 0.66 mmol), (2R,4S)-N-allyloxycarbonyl-2-(2-azetidinon-3-ylmethyl)-4-mercaptopyrrolidine (180 mg, 0.66 mmol) and N,N-diisopropylethylamine (0.12 ml, 0.66 mmol) to obtain allyl (1R,5S,6S)-2-[(2R,4S)-N-allyloxycarbonyl-2-(2-azetidinon-3-ylmethyl)pyrrolidin-4-ylthio]-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate (125 mg, yield: 36.3%) in the form of foam.
