Abstract :In this work, an efficient, easy, and green process has been developed for the synthesis of 2,3-dihydroquinazolin-4insert ignore into journalissuearticles values(1H);-one from a condensation reaction of anthranylamide with various aromatic aldehyde using of phosphate fertilizers, mono-ammonium phosphate insert ignore into journalissuearticles values(MAP);, di-ammonium phosphate insert ignore into journalissuearticles values(DAP); and triple super phosphate insert ignore into journalissuearticles values(TSP); as heterogeneous catalysts. The reaction conditions were optimized taking into account of some parameters which control the reaction, namely the nature and the volume of the solvent and the mass of catalyst. The results show that the catalysts used herein are very interesting because they present a good catalytic activity and they are reusable for at least five cycles without any degradation of their activity .
