Abstract
Preparation procedure for N-acyl-derivatives of 7-aminocephalosporanic acid, characterized in that a dimethylformiminium N-halide-halosulfite of formula **(See formula)** where X = chlorine, bromine, iodine, with a carboxylic acid of the following general formula R - COOH R being an aromatic, alkanoaromatic, heterocidic group, suspended or dissolved in an inert medium and at a temperature of -20 to + 20º; the resulting mixture is then added gradually, over a solution or suspension of a 7-aminocephalosporanic acid of formula **(See formula)** R1 being an ester, hydroxyl, quaternary N-pyridinium group and R2 being hydrogen, an alkali metal, alkaline earth metal, benzathine salt, or internal salt in the case of N-pyridinium compounds, to form an N-acyl- derived from the formula **(See formula)** where R, R1 and R2 have the significance given above, which is isolated by precipitation, by dilution of the reaction mixture in an aliphatic hydrocarbon of 6 to 10 carbon atoms.
