Reaction Steps

7-([3,3′]Bipyridinyl-5-yl)carbonyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole was synthesized in substantially the same manner as in step c) of Synthesis Example 1, except that 263 mg of 7-([3,3′]bipyridinyl-5-yl)carbonylimidazo[5,1-b]thiazole, 0.316 ml of tri-n-butylstannyl chloride, and 1.72 ml of a 1.0 N lithium bis(trimethylsilyl)amide/THF solution were used as the starting compounds and, due to the unstable nature of the tin compound, the purification by column chromatography on silica gel was not carried out. 4-Nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-[7-([3,3′]bipyridinyl-5-yl)carbonylimidazo[5,1-b]-thiazol-2-yl]-1-carbapen-2-em-3-carboxylate (80 mg) was prepared in substantially the same manner as in step a) of Example 1, except that 270 mg of 4-nitrobenzyl (1R,3R,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-oxo-1-carbapenam-3-carboxylate and 7-([3,3′]bipyridinyl-5-yl)carbonyl-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds.
