Abstract
Process for the preparation of 1H-benzimidazoles substituted in position 2, preferably those corresponding to the general formula <IMAGE> in which R1 represents a linear or branched alkyl containing 1 to 13 carbon atoms, a phenyl, halophenyl, 4-nitrophenyl, 4-methylphenyl, 4-cyanophenyl, 4-carboxyphenyl, benzyl, thienyl, furanyl, pyridyl, or 1,3- or 1,4-phenylene, R2 represents a hydrogen or chlorine atom, nitro or carboxyl, 2-(4-chlorophenyl)-1H-benzimidazol-5-yl, or 2-(4-carboxyphenyl)- 1H-benzimidazol-5-yl, and n is equal to 1 or 2. According to the invention, an aldehyde, a thionyl halide and a nitrogen-containing aromatic heterocyclic compound are reacted together, the product formed is then reacted with an optionally substituted 1,2-benzenediamine and the 1H-benzimidazole thus obtained is separated from the reaction mixture. Using this process, 1H-benzimidazoles are obtained in a single stage, under moderate conditions, with very high yields.
