Several benzimidazole N-oxide derivatives were synthesized in very good yield by heating at reflux the corresponding N-alkyl-2-nitroaniline derivative with NaOH in 60% 1,4-dioxanewater. The effect of substituents on the aromatic ring and amino group on the reaction is discussed.Key words: synthesis, benzimidazole N-oxides.
