Product 1

HCID 910680634-Nitrobenzyl (1s,5r,6s)-6-((1r)-1-hydroxyethyl)-1-methyl-2-[7-(thiazol-5-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-1-carbapen-2-em-3-carboxylateYield 85.2%

Procedure

4-Nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-[7-(thiazol-5-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-1-carbapen-2-em-3-carboxylate (244 mg) was prepared in the same manner as in step a) of Example 1, except that 179 mg of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 260 mg of 7-(thiazol-5-yl)carbonyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds.
