ilica gel supported Phosphomolybdic acid (PMA.SiO 2 ) catalyzes efficiently the one‐pot three‐component coupling reaction of anthranilic acid, orthoesters, and amines at room temperature to afford 4(3 H )‐Quinazolinones in high to excellent yields under solvent‐free conditions. The supported catalyst can be recovered and reused. J. Heterocyclic Chem., (2010).
