A consecutive condensation, cyclization, and dehydration of 2-(1H-benzo[d]imidazol-2-yl) anilines and ketonic acid in toluene catalyzed by TsOH gave a series of benzo[4,5]imidazo [1,2-c]pyrrolo[1,2-a]quinazolin-3(2H)-one derivatives in good to high yields. The structure of 3e was further confirmed unambiguously by X-ray diffraction analysis.
