Abstract

A new synthetic route to 3-substituted-4(3H)-quinazolinone has been developed using Potassiumcarbonate-silica as a solid support under microwave irradiation which is an environmental friendly procedure. The use of basic catalyst under solvent free condition for the ring closure of this heterocyclic system is notable.
