Abstract

A number of esters of some β-(2-azolyl)acrylic acids were synthesized by means of the Wittig reaction and subjected to hydrolysis. The reaction of β-(1-methyl-2-benzimidazolyl)-acrylic acid and its derivatives with bromine was studied. It is shown that 1-methyl-2-ethynylbenzimidazole and 1,2-dimethylbenzimidazole are formed when methyl α-bromo-β-(1-methyl-2-benzimidazolyl)-acrylate is refluxed in sodium bicarbonate solution.
