Reaction Steps

A mixture of 2-bromo-7α-methoxy-3-methyl-4-phenylcarbonyl-3-cephem 1,1-dioxide (130 mg) and silver benzoate (115 mg) in acetonitrile (10 ml) was stirred at room temperature for 30 minutes. The reaction mixture was diluted with EtOAc, then filtered and the filtrate was rotoevaporated. The residue was purified by flash chromatography (eluting with n-hexane/EtOAc mixtures) affording the title product as a white powder (85 mg) IR (KBr) 1805, 1740, 1675.
