Product 1

HCID 914289404-Nitrobenzyl (1s,5r,6s)-6-((1r)-1-hydroxyethyl)-1-methyl-2-[7-(pyridin-4-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-1-carbapen-2-em-3-carboxylateYield 58.4%

Procedure

4-Nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-[7-(pyridin-4-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-1-carbapen-2-em-3-carboxylate (1.23 g) was prepared in the same manner as in step a) of Example 1, except that 1.33 g of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 2.00 g of 7-(pyridin-4-yl)carbonyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds.
