Reaction Steps

To 3-[[[(2S,4S)-4-mercapto-1-(4-nitrobenzyloxy)carbonyl-2-pyrrolidinyl]carbonyl]amino]benzoic acid (7.68 g) in DMF (30 mL), p-nitrobenzyl (1R,5R,6S)-6-[(1R)-1-hydroxyethyl]-2-[(diphenylphosphono)oxy]-1-methylcarbapen-2em-3-carboxylate (10 g) was added. To the reaction mixture N,N-diisopropylethylamine (4.78 g) was added at −30° C. and stirred. After completion of reaction, the reaction mass was poured into water and ethyl acetate mixture at 10° C. The layers were separated and organic layer washed with brine solution. The organic layer was subjected to carbon treatment and taken for subsequent step.
