A new synthetic route towards benzimidazo[2,1-b]quinazolin-12-ones has been developed, which relies on the Pd-catalyzed intramolecular aminocarbonylation of N-(2-bromophenyl)-1H-benzimidazol-2-amines. Using near stoichiometric amounts of 13CO, isotopically labelled benzimidazo[2,1-b]quinazolin-12-ones were synthesized.
