Abstract
A process for preparing 3- (2-quinoxalinylmethylene) carbazate-n1, n4-methyl-dioxide, which is characterized by contacting a member selected from the group consisting of 3- (2-quinoxalinylmethylene) carbazate-n1, n4- alkyl dioxide, in which the alkyl has from 2 to 18 carbon atoms; 3- (2-quinoxalinylmethylene) -carbaza-to-n1, n4-cyclohexyl dioxide and 3- (2-guinoxalinylmethylene) carbazate-n1, n4-tetrahydrofuryl dioxide, with methanol, in the presence of a concentrated acid, at a temperature from 25 to 200º c., until the reaction material materially ends and a resulting crystalline product is recovered.
