Abstract
The reaction of 2-aminomethyl- and 2-aminomethyl-1-methylbenzimidazoles with nitrous acid was investigated. The reaction proceeds with nitrogen evolution with excess hydrochloric or hydrobromic acids to form 2-chloro- and 2-bromomethylbenzimidazoles, while 2-benzimidazolylmethylnitrolic acids and other products are obtained with excess nitrous acid.
