An efficient three-component synthesis of benzimidazo[1,2-a]quinoline-6-carbonitriles is described. Condensation reaction of a benzene-1,2-diamine and a cyclohexane-1,3-dione gave an enamine intermediate, which on treatment with an arylidenemalononitrile in water–ethanol (1:1) afforded the title compounds in good to excellent yields.
