Abstract

A new path for the synthesis of 3-monoalkyl- and 3,6-dialkyl-substituted benzo[1,2-d:3,4-d']-diimidazole is described: 5-tosylamino-1-alkylbenzimidazole is converted to the 4-nitro derivative by nitration in glacial acetic acid, and the imidazole ring is closed after alkylation and cleavage of the tosyl group.
