Abstract

Recently, Katritzky and coworkers in a series of papers described preparation of various 1-(1-aryl/alkylaminoalkyl)benzotriazoles by reaction of benzotriazole, an aliphatic aldehyde (or the product of their reaction - 1-(1-hydroxyalkyl)benzotriazole) and an amine in ethanol. In some cases the formation of 1-bis(1-benzotriazolylalkyl)aryl/alkylamines was also observed. The aim of our study was to compare the reactivity of 2-, 3- and 4-aminopyridine in the reaction with 1-hydroxymethylbenzotriazole, and to find out whether and under which conditions also 1-hydroxymethylbenzimidazole enters an analogous reaction. We further studied the reaction of these two compounds with 5-amino-1-arylbenzazoles and the structure of the products.
