Abstract
The carbazates of formula I are obtained by reacting the quinoxaline N<1>,N<4>-dioxides carrying in position 2 a chloromethyl or bromomethyl group with one to two equivalents of an alkali metal carbonate and one to two equivalents of a hydrazine of formula R''NH-NH-COOCH3 at a temperature of between 75 and 85 DEG C and in an inert solvent. This hydrazine is prepared by reaction of methyl carbazate with a corresponding acid anhydride or sulphonyl halide which introduces the radical R''. The meaning of the symbols is explained in Claim 1. The compounds of formula I are strong antibacterial agents.
