Abstract
The condensation of 2-(2-aminophenyl)benzimidazoles 2, prepared starting from o-phenylenediamines, with the diethylacetylenedicarboxylate in ethanol afforded a new derivatives of benzimidazo[1,2-c]quinazoline 3 with satisfactory yields. The exact structure of 3a was established by X-ray diffraction.
