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