A simple, efficient and general method has been developed for the synthesis of 2-hetero substituted -4-quinazolones by using Niementowski reaction. The synthetic reaction involves thermal condensation and cyclisation of a drug amide with anthranilic acid and 6, 8–dibromo anthranilic acid at elevated temperatures to yield the hetero-moieties namely carbamazepinyl –4–quinazolone and 6, 8- dibromo-2-carbamazepinyl-4-quinazolone. The structures of the compounds were characterized by IR, NMR, MS and elemental analysis. The compounds were evaluated for antimicrobial activity.
