Abstract

The derivative of triazolo/benzimidazoquinazolinones is prepared via silica-promoted solvent-free method using microwave irradiation with an excellent yield. The newly synthesized compounds were characterized by various techniques like IR, NMR and Mass spectroscopy. The compound with 1a was crystallized and analysed by single crystal X-ray diffraction studies.

An efficient microwave-assisted silica-promoted, solvent-free synthesis of trizaolo/benzimidazoquinazolinones (1a–2h) with an excellent yield are reported and component 1a is crystallized and analysed by single crystal X-ray diffraction studies.
