Benzimidazoles and their derivatives have a wide spectrum of biological activity. For 
example, among heterocyclic compounds containing a benzimidazole skeleton, there are 
a number of effective drugs that are recommended for use in agriculture (
albendazole, 
carbendazim, benomyl
) and medicine (
dibazole
). Therefore, conducting targeted 
research on the synthesis and study of the biological activity of substituted 
benzimidazoles is of both theoretical and practical interest [1-3]. 
In this work, we curried out interaction of 2,5-dimethylbenzimidazole (
1
) with 
substituted arylsulfonyl chlorides. The aim of this work to study “
structure-biological 
activity
” relationship of the synthesized arylsulfonyl derivatives of benzimidazoles: 
Arylsulfonylation of 2,5-dimethylbenzimidazole (
1
) with substituted arylsulfonyl 
chlorides curried out in the presence of triethylamine at room temperature for 4 hours. 
As results we have synthesized corresponding N
