Reaction Steps

4-Nitrobenzyl (1S,5R,6S)-2-[7-[5-(2-azidoethylthio)pyridin-3-yl]carbonylimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate (370 mg) was prepared in the same manner as in step a) of Example 1, except that 485 mg of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 857 mg of 7-[5-(2-azidoethylthio)pyridin-3-yl]carbonyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds.
