PROCEDURE

实验过程

A solution of m-chloroperbenzoic acid (7 g) in ethyl acetate (35 ml) was added to a solution of benzhydryl 7-phenylacetamido-3-(2,2-dichlorovinyl)-2-cephem-4-carboxylate (15 g) in ethyl acetate (75 ml) under ice-cooling and the mixture was stirred at the same temperature for an hour. The precipitates were collected by filtration to give benzhydryl 7-phenylacetamido-3-(2,2-dichlorovinyl)-3-cephem-4-carboxylate-1-oxide (6.57 g).
