Procedure

To a solution of 4-nitrobenzyl (1R,5R,6S)-6-[(1R)-1-hydroxyethyl]-1-methyl-2-(diphenylphosphoryloxy)-1-carbapen-2-em-3-carboxylate (0.66 g) in anhydrous acetonitrile (5 ml), N,N-diisopropylethylamine (0.19 ml) and a solution of (2S,4S)-4-mercapto-1-methyl-2-[(3R)-3-(N-methyl-N-4-nitrobenzyloxycarbonylaminomethyl)pyrrolidin-1-ylcarbonyl]pyrrolidine (0.53 g) in anhydrous acetonitrile (5 ml) were added while stirring in an ice bath. The resulting mixture was allowed to react overnight at 0° C. To the reaction mixture, ethyl acetate was added. The resulting mixture was washed with water and saturated saline solution, dried over anhydrous sodium sulfate and then concentrated by evaporation under reduced pressure. The residue was purified by chromatography through a silica gel column (ethyl acetate/methanol=6/4), whereby 4-nitrobenzyl (1R,5S,6S)-6-[(1R)-1-hydroxyethyl]-1-methyl-2-[(2S,4S)-1-methyl-2-[(3R)-3-(N-methyl-N-4-nitrobenzyloxycarbonylaminomethyl)pyrrolidin-1-ylcarbonyl]pyrrolidin-4-ylthio]-1-carbapen-2-em-3-carboxylate (0.43 g) was obtained.
