An optimization of Grimmel’s method under microwave irradiation is reported here for the first time to synthesize 4-amino-N-(4-oxo-2-substituted-4H-quinazolin-3-yl)benzenesulfonamidederivatives. The method was successfully applied for the synthesis of 2-alkyl and 2-aryl substituted derivatives. However, unexpected results were obtained when the same protocol was applied for 2-styryl-substituted quinazolinones
