Reaction Steps

Iodomethane (0.84 g) is added to 37.0 mg of allyl(1R,5S,6S)-2-[(3S,5S)-1-allyloxycarbonyl-5-[N-(imidazo[5,1-b]thiazol-5-yl)methyl-N-methylaminocarbonyl]pyrrolidin-3-yl]thio-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate, and the mixture is stirred in an argon atmosphere in a light-shielded state at room temperature for 18 hr. The excess reagent is removed by evaporation under reduced pressure, and the residue is purified by column chromatography on Sephadex LH-20 (chloroform:methanol=1:1) to give 36.3 mg of allyl(1R,5S,6S)-2-[(3S,5S)-1-allyloxycarbonyl-5-[N-methyl-N-(6-methylimidazo[5,1-b]thiazolium-5-yl)methylaminocarbonyl]pyrrolidin-3-yl]thio-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate iodide as a milky white amorphous material.
