Synthesis of Some Benzimidazole-substituted Benzotriazoles
Abstract
2-Alkylsubstituted benzimidazoles (3a–h) were prepared from the acid-catalyzed reaction of 4-methyl-1,2-phenylenediamine with corresponding carboxylic acids. Addition of these benzimidazoles to N-chloromethylbenzotriazole in the presence of sodium amide under reflux conditions gave the novel benzimidazole-substituted benzotriazoles (5a–f). IR and 1HNMR spectroscopy and elemental analysis were used for the identification of these compounds.
