Procedure

The procedure of Example 1a) was repeated, except that 424 mg of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 658 mg of 7-benzylthio-2-(tri-n-butylstannyl) imidazo[5,1-b]thiazole were used as the starting compounds. Thus, 459 mg of 4-nitrobenzyl (1S,5R,6S)-2-(7-benzylthioimidazo[5,1-b]thiazol-2-yl)-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate was prepared.
