Abstract
An efficient synthesis of 4(3H)-quinazolinones by coupling of anthranilic acid, ortho esters and amines using Polymer supported ferric chloride catalyst under solvent free conditions is described. This new approach consistently has the advantage of excellent yields (80-97%) and short reaction times of 5-15 min.
