ecarbonitriles 4a–r were prepared via either regioselective reaction of 3-aryl-1-(1H-benzimidazol-2-yl)-2-propen-1-ones 3 with malononitrile or ylidenemalononitriles 6 with 2-acetyl-1H-benzimidazoles 1 in the presence of sodium alkoxide in the corresponding alcohol. All the synthesized compounds showed significant vasodilation properties using isolated thoracic aortic rings of rats pre-contracted with
