A convenient copper-catalyzed domino method for the synthesis of benzimidazo[2,1-b]quinazolin-12(6H)-ones has been developed via reactions of readily available substituted 2-bromo-N-(2-halophenyl)benzamides with cyanamide, in which cyanamide acts as a useful building block. Copyright

The reaction of methyl anthranilates with N-arylcyanamides in the presence of p-TsOH in t-BuOH under reflux afforded predominantly 3-arylquinazolin-4-ones. In contrast, the reaction of the same reactants with TMSCl in t-BuOH at 60 °C followed by the Dimro
