Abstract

Procedure for obtaining substituted N, N'-dioxo-quinazolines, specifically of the formula **(See formula)** where A is chosen from the radicals of the group consisting of guanyl (-C (= NH) -NH2), carboxymethyl (-COO-CH3) and acetyl (-CO-CH3), characterized in that 2-dichloromethyl-N is condensed, N'-dioxoquinoxaline with a hydrazimic derivative of the formula H2N-NH-A, or an acidic addition salt thereof, carrying out the reaction in a hydro-alcoholic solvent, in the presence of an organic acid-binding base and at the reflux temperature of the mixture.
