Abstract
Procedure for the preparation of a new cephalosporin derivative of general formula: **(See formula)** wherein R represents an alkyl radical containing from 1 to 4 carbon atoms, straight or branched chain, or phenylalkyl, whose alkyl part contains from 1 to 4 carbon atoms, straight or branched chain; n is an integer equal to zero, 1 or 2; R1 represents a (methyl-5-thiadiazol-1,3,4 yl-2) thio radical or (methyl-1 tetrazol-1,2,3,4 yl-5) thio and R2 represents a carboxy radical or R1 represents the pyridinium radical and R2 represents the carboxylate ion, with the exception that when R simultaneously represents an alkyl radical, R1 represents the pyridinium radical and R2 represents the carboxylate ion, n is necessarily an integer equal to 1 or 2, characterized in that it is react methyl-5 thioxo-2 thiadiazo1-1, 3, 4 ina, methyl-1 thioxo-5 tetrazol-l, 2, 3, 4 ina or pyridine on a product of general formula **(See formula)** where R represents an alkyl radical containing 1 to 4 straight or branched chain or phenylalkyl carbon atoms, the alkyl part of which contains 1 to 4 straight or branched chain carbon atoms and n is an integer equal to 0, 1 or 2, then eventually, when the symbol R2 represents the carboxy radical, the product obtained is transformed into a metal salt or an addition salt with a nitrogenous base.
