Procedure

The procedure of Example 23-a) is repeated to prepare 653.0 mg of a mercaptan compound as a yellow oil from 766.4 mg of (3S,5S)-3-acetylthio-1-allyloxycarbonyl-5-(5-methylimidazo[5,1-b]thiazol-2-yl)methylpyrrolidine described in Synthesis Example 11. Allyl(1R,5S,6S)-2-[(3S,5S)-1-allyloxycarbonyl-5-(5-methylimidazo[5,1-b]thiazol-2-yl)methylpyrrolidin-3-yl]thio-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate (560.2 mg) is prepared as a colorless amorphous material from this mercaptan and 891.6 mg of allyl(1R,5R,6S)-2-(diphenylphosphono)oxy-6-((1R)-1-hydroxyethyl)-1-methylcarbapen-2-em-3-carboxylate.
