Participants

Reaction Steps

With 54.5 mg (0.34 mmol) 1,1′-carbonyldiimidazole, 53.0 mg (0.34 mmol) (2-aminothiazole-4-yl)-acetic acid and 182.0 mg (0.28 mmol) (E)-(6R,7R)-7-amino-3-[1-[1-[(4-hydroxy-phenylcarbamoyl)-methyl]-pyridin-1-ium-4-ylmethyl]-2-oxo-pyrrolidin-3-ylidenemethyl]-8-oxo-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylate trifluoroacetate in 4 ml N,N-dimethylformamide. The resulting solid was purified by reversed phase chromatography (RP-18 LiChroPrep gel, water:acetonitrile=9:1). The organic solvent was stripped off at a rotary evaporator and the aqueous phase was freeze-dried.
