Abstract

On fait réagir le 2-méthylquinoxaline- 1,4-di-N-oxyde avec un nitrite organique de formule R-NO 2 , dans laquelle R est un alcoyle à 1-4 atomes de carbone, le produit obtenu est mis en réaction en solution avec le carbazate de méthyle et la carbométhoxy-hydrazone de 2-formylquinoxaline- 1,4-di-N-oxyde est séparée par précipitation pour obtenir la carbomé-thoxy-hydrazone de 2-formylquinoxaline-1,4-di-N-oxyde de la formule :2-methylquinoxaline-1,4-di-N-oxide is reacted with an organic nitrite of the formula R-NO 2, in which R is an alkyl of 1-4 carbon atoms, the product obtained is reacted in solution with methyl carbazate and 2-formylquinoxaline-1,4-di-N-oxide carbomethoxy-hydrazone is separated by precipitation to obtain 2-formylquinoxaline-1,4-di-N-carbome-thoxy-hydrazone oxide of the formula:
