A facile, rapid and one‐pot procedure for the synthesis of some new 2,4(1H,3H)‐quinazolinediones is described. The method involves the one‐pot condensation of isatoic anhydride, primary amine and carbonyl diimidazole (CDI) in the absence of organic or inorganic catalyst. It affords the corresponding product in high yield.
