Procedure

The procedure of Example 1a) was repeated, except that 762 mg of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 1.10 g of 5,7-bis(methylthio)-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds. Thus, 720 mg of 4-nitrobenzyl (1S,5R,6S)-2-[5,7-bis(methylthio)imidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate was prepared.
