Abstract

The invention comprises the compounds of the formulae <FORM:0916456/IV (b)/1> and <FORM:0916456/IV (b)/2> together with their preparation by reacting, in the presence of a solvent and in the presence of pyridine as an acid binding agent, 4-amino - 2,3 - dimethyl-1-phenyl-3-pyrazolin-5-one with either p-benzoic acid sulphochloride or benzoyl chloride p-sulphonamide. Benzoyl chloride p-sulphonamide is obtained by reacting the corresponding acid with thionyl chloride, and p-benzoic acid sulphochloride by the action of chlorosulphonic acid on sodium p-carboxybenzenesulphonate.
