Procedure

4-Nitrobenzyl (1S,5R,6S)-2-(7-chloroacetylimidazo-[5,1-b]thiazol-2-yl)-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate (1.01 g) was prepared in the same manner as in step a) of Example 1, except that 2.85 g of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 1.66 g of 7-chloroacetyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds.
