A three component cyclocondensation of p-(dimethylamino)benzaldehyde with 3,5-dimethoxyaniline and 2-phenacyl-1H-benzimidazoles gives previously unknown 2-aryl-3-(1H-benzimidazol-2-yl)-5,7-dimethoxyquinolines. The Hanztsch type reaction occurs in refluxing acetic acid and is accompanied by aromatization of the 1,4-dihydroquinolines formed through loss of N,N-dimethylaniline.
