Abstract

Procedure for the preparation of di-N-oxides- (1,4) quinoxalines 2-methyl-3-carboaxides, characterized in that benzofuroxanes of formula **(See formula)** in which R1 represents hydrogen, low molecular weight alkyl and alkoxy radicals, as well as chlorine, are reacted, in the presence of ammonia or primary amines, in an organic solvent at a temperature between 2o ° and 100ºC approximately with acetoacemides of general formula (II) **(See formula)** wherein: R2 represents hydrogen, a straight-chain or branched alkyl radical optionally substituted by a hydroxy, low-molecular-weight alkoxy, carbalkoxy, mono- or dialkylamino radical; R3 can represent hydrogen and in addition, it can be equal to or different from R'' and, in the case of R2 being hydrogen, R3 can also represent the cyclohexyl radical and, in the event that R2 and R3 signify, alkyl, these alkyl radicals together with the amide nitrogen atom they can be components of a heterocyclic ring containing 5 or 6 members.
