Abstract
A process for the preparation of a cephalosporin compound, comprising the steps of a) forming a penicillin 1-beta-oxide having a protective ester group in the 3-position; b) converting said δ 3-3-methyl-cephalosporin ester, and c) removing the side chain in position 7- of said cephalosporin ester, to form a corresponding ester of 7-beta-amino-cephalosporin, characterized in that the protective ester group in the 3- position of penicillin 1-beta-oxide and in the 4- position of the cephalosporin compounds is, throughout the process, a diphenylmethyl ester group.
