Twenty 2,3-disubstituted-4(3H)-quinazolinones were synthesed by one-pot three-component method with isatoic anhydride, orthoesters and amines as raw materials in the presence of KAl(SO4)2·12H 2O (Alum) under microwave irradiation and solvent-free conditions. 6-Bromo-2-propyl-3-p-tolylquinazolin-4(3H)-one (4m), 6-bromo-2-methyl-3- phenethylquinazolin-4(3H)-one (4n) and 6-bromo-2-ethyl-3-phenethylquinazolin- 4(3H)-one (4o) were characterized by IR, 1H NMR, 13C NMR and elemental analysis.
