VERFAHREN ZUR HERSTELLUNG VON 3-AMINOBENZO-1,2,4-TRIAZIN-DI-N-OXIDEN (1,4)

摘要

1,2,4-Benzotriazines-1,4-di-N-oxides having an amino compound in the 3-position, preferably with a further substituent in one or both of the 6- and 7-positions, are antimicrobial agents. The compounds, of which 6-chloro-3-amino-1,2,4-benzotriazine-1,4-di-N-oxide and 7-chloro-3-amino-1,2,4-benzotriazine-1,4-di-N-oxide are typical examples, are prepared through treatment of the appropriately substituted benzofuroxan with cyanamide under basic conditions followed by acidification.
