Benzyl Bromide → 4-Nitrobenzyl (1s,5r,6s)-2-[7-(1-benzylpyridinium-3-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-6-((1r)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate bromide

Reaction Steps

4-Nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-[7-(pyridin-3-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-1-carbapen-2-em-3-carboxylate (78.1 mg) was suspended in 1.5 ml of acetonitrile to prepare a suspension. Benzyl bromide (0.032 ml) was added to the suspension, and the mixture was stirred at room temperature for 10 hr. The reaction solution was concentrated under the reduced pressure to give 4-nitrobenzyl (1S,5R,6S)-2-[7-(1-benzylpyridinium-3-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate bromide.
