Reaction Steps

(E)-(6R,7R)-7-(2-bromo-acetylamino)-3-[1-[1-[(3-fluoro-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 (see ex. C1a) (300.0 mg, 0.45 mmol) was dissolved in 3 ml N,N-dimethylformamide, then 4-mercaptophenol (58.0 mg, 0.45 mmol), followed by triethylamine (62.7 ml, 0.45 mmol) was added. After 22 h the reaction mixture was poured on diethyl ether and the solid was collected by filtration. The brown solid material was suspended in water: acetonitrile (1:1) and chromatographed on MCI gel (75-150μ, Mitsubishi Kasei Corporation) with a gradient of water: acetonitrile (9:1, 4:1, 3:1). The organic solvent was stripped off at a rotary evaporator and the aqueous phase was freeze-dried.
