A useful approach for the synthesis of pharmacologically active tetrahydropyridinylbenzimidazoles is described. 2-Pyridin-3-ylbenzimidazoles 3a-d have been synthesized by condensation of 3-pyridinecarbox-aldehyde 1 with substituted 1,2-phenylenediamines 2a-d following oxidative cyclization with iodobenzene diacetate. Methylation of 3a-d with iodomethane and potassium hydroxide, subsequent formation
