Synthesis of the potent mutagen 3,5,8-trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine.

Abstract

The mutagenic title compound (5,8-DiMeIQx) was synthesized by two different routes: from 2-methyl-4,6-dinitroaniline; and from 4-chloro-2-methyl-6-nitroaniline. The latter and more convenient route involved 2,1,3-benzoselenadiazole intermediates.
