FREMGANGSMAADE TIL FREMSTILLING AF 3-KARBAMOYLOXYMETYLCEPHALOSPORINFORBINDELSER

A process for the preparation of a 3-carbamoyloxymethyl cephalosporin compound which comprises hydrolyzing a 3-phosphonocarbamoyloxymethyl cephalosporin compound. The hydrolysis is preferably effected at a pH in the range of pH3 to 4, for example using aqueous sodium hydrogen carbonate.
