Abstract
A process for the preparation of methyl 3- (2-quinoxalinylmethylene) carbazate N1, N4-dioxide, characterized by contacting a derivative of 2-quinoxalincarboxaldehyde N1, N4-dioxide with at least approximately an equimolar proportion of a carbazate in a reaction inert solvent in the presence of a strong acid catalyst, at a temperature of approximately 30º to 200ºC, until the reaction is practically complete, selecting the derivative of the nitrone, acetal, oxime, semicarbazone and thiosemicarbazone derivatives of 2-quinoxalincarboxaldehyde dioxide; carbazate is selected from methyl and 3-lower-alkylene-, cyclopentyliden-, cyclohexylidene-, and benzylidene-carbazates, with the proviso that when the derivative is acetal, the carbazate is not methyl carbazate.
