Procedure

To a solution of 230.0 mg (0.34 mmol) (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 in 5 ml N,N-dimethylformamide was added 40.0 mg (0.37 mmol) 4-methyl-4H-[1,2,4]triazole-3-thiol. After 1 h 47.0 μl (0.34 mmol) triethyl amine was added and stirring was continued for 12 h. The solution was poured on diethyl ether and 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, 2:1). The organic solvent was stripped off at a rotary evaporator and the aqueous phase was freeze-dried.
