Procedure
With 121.1 mg (0.75 mmol) 1,1,-carbonyldiimidazole, 170.6 mg (0.75 mmol) 2-(3,4-dimethoxyphenylthio)acetic acid and 250.0 mg (0.62 mmol) (E)-(6R,7R)-7-amino-3-[1-(3-hydroxy-benzyl)-2-oxo-pyrrolidin-3-ylidenemethyl]-8-oxo-5-thia- 1-aza-bicyclo[4.2.0]oct-2-ene2-carboxylic acid trifluoroacetate in 4 ml N,N-dimethylacetamide. The resulting solid was purified by column chromatography on MCI gel (75-150μ, Mitsubishi Kasei Corporation) with a gradient of water:acetonitrile (1:0, 4:1, 3:1). The organic solvent was stripped off at a rotary evaporator and the aqueous phase was freeze-dried.
