Abstract

The novel process for the preparation of methyl 3-(2-quinoxalinylmethylene)carbazate N1, N4-dioxide which comprises contacting methyl 3-(2-quinoxalinylmethylene)carbazate with oxidizing agent in reaction-inert solvent at a temperature of from about 20 DEG C. up to 100 DEG C. until reaction is substantially complete, said oxidizing agent being selected from the group consisting of peracetic acid, perbenzoic acid, m-chloroperbenzoic acid, perphthalic acid, performic acid, trifluoroperacetic acid and hydrogen peroxide.
