PROCESS FOR PREPARING NEW DERIVATIVES OF 2-FORMYL-3-CARBOXAMIDOCHINOXALIN-DI-N-OXIDES

摘要

2-Formyloximido-3-aminocarbonylquinoxaline-1,4-di-N-oxides are antimicrobial agents. The compounds, of which 2-formylcarbomethoxyhydrazine-3-dimethylaminocarbonylquinoxaline-1,4-d i-N-oxide is a typical embodiment, are prepared from the reaction of the corresponding 2-bis(halogeno) methyl-quinoxaline derivative and hydroxylamine or an appropriate hydrazinocarbonic acid ester in the presence of a primary or secondary amine and water.
