실험 절차
4-Nitrobenzyl (1S,5R,6S)-2-[7-(2-bromoethyl)thioimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate (177 mg) was dissolved in 5 ml of acetonitrile. 1,4-Diazabicylco[2,2,2]octane (43 mg) was added to the solution. The mixture was stirred at 50° C. for 12 hr. The reaction solution was concentrated, and the residue was purified by column chromatography on Sephadex LH-20 (chloroform:methanol=1:1) to prepare 184 mg of 4-nitrobenzyl (1S,5R,6S)-2-[7-[2-(1-azonia-4-azabicyclo-[2,2,2]oct-1-yl)ethyl]thioimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate bromide.
