Abstract

Process for the preparation of carbomethoxy hydrazone of 1,4-dioxide-2-formylquinoxaline, characterized in that benzofuran-N-oxide is reacted with methyl bis-carbazate pyruvaldehyde in molar ratio between 1: 2 and 1: 2.5, in solution in an organic solvent and in the presence of an organic base as a catalyst, at a temperature comprised between 10º and 150º c.
