Abstract

Procedure for obtaining a new cephalosporic derivative, characterized in that said antibiotic having the structural formula: ** (Formula) ** where X = H, Na, K ... is obtained by reacting the tributyltin ester of 7-amino-3-methyl-3-cephem-4-carboxylic acid with a functional derivative of the (-) isomer of alpha-amino-alpha- (4-hydroxyphenyl) acetic acid in the presence of a carbonyldiimidazole type agent, or a carbodiimide, such as N, N'' - diethyl-, -dipropyl-, or -diisopropyl- carbodiimide, or preferably N, N'' - dicyclohexylcarbodiimide, within inert solvents such as tetrahydrofuran, methylene chloride or acetonitrile and the subsequent removal of the various protecting groups.
