PROCEDURE

实验过程

The procedure of Example 23-a) is repeated, except that 303.0 mg of (3S,5S)-1-allyloxycarbonyl-3-benzoylthio-5-(5-chloroimidazo[5,1-b]thiazol-2-yl)methylpyrrolidine described in Synthesis Example 23 is used. Thus, 261.0 mg of a mercaptan compound is prepared as a yellow oil. Allyl(1R,5S,6S)-2-[(3S,5S)-1-allyloxycarbonyl-5-(5-chloroimidazo[5,1-b]thiazol-2-yl)methylpyrrolidin-3-yl]thio-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate (186.7 mg) is prepared as a colorless amorphous material from this mercaptan and 260.9 mg of allyl(1R,5R,6S)-2-(diphenylphosphono)oxy-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate.
