Silica gel supported Phosphomolybdicacid (PMA.SiO2) catalyzes efficiently the one‐pot three‐component coupling reaction of anthranilic acid, orthoesters, and amines at room temperature to afford 4(3H)‐Quinazolinones in high to excellent yields under solvent‐free conditions. The supported catalyst can be recovered and reused. J. Heterocyclic Chem., (2010).
