An efficient strategy for the preparation of a novel heterocyclic ring system of benzimidazoquinazolines with three-point diversity has been described. The compounds were obtained by treating o-phenylene diamines with o-nitrobenzaldehyde to give benzimidazoles, followed by reduction of the nitro group to give an amine. Derivatization of the resulting amine with isothiocyanates followed by in situ cyclodesulfurization at rt furnished the title compounds in high yields and purities.
