Abstract
2-Hydroxymethylbenzimidazole was synthesized by the cyclization of o-phenylenediamine with glycolic acid. Its interaction with arylsulfonyl chlorides in the presence of triethylamine showed that in addition to the expected 1-arylsulfonyl-2-hydroxymethylbenzimidazoles, the formation of 1-arylsulfonyl-2-chloro-methylbenzimidazoles was observed. It turned out that an increase in the quantity of arylsulfonyl chlorides was capable of increasing the fraction of 1-arylsulfonyl-2-chloromethylbenzimidazoles.
