A one-pot procedure for the synthesis of substituted benzimidazo[1,2-a]quinolines from the corresponding benzimidazoles and 2-bromobenzaldehydes has been developed. The titled products were prepared through Knoevenagel condensation and copper-catalyzed intramolecular Ullmann-type coupling in moderate to good yields. Knoevenagel condensation - copper catalyst - Ullmann coupling - quinoline synthesis
