Mezlocillin, (2S,5R,6R)-3,3-dimethyl-7-oxo-6-[(R)-2-[(3-methylsulfonyl)-2- oxoimidazolidin-1-carboxamido]-2-phenylacetamido]-4-thia-1-azabicyclo[3.2.0]-heptan-2- carboxylic acid (32.1.1.27), is synthesized by acylating ampicillin (32.1.1.16) with 3-chlorocarbonyl-1-methansulfonyl-2-imidazolidinone (32.1.1.26) in the presence of triethylamine. The necessary 3-chlorocarbonyl-1-methansulfonyl-2-imidazolidinone (32.1.1.26) is synthesized by sulfonating 2-imidazolidinone with methanesulfonyl chloride, which forms 1-methanesulfonyl-2-imidazolidinone (32.1.1.25) and its subsequent reaction with phosgene.
