One-Pot Synthesis of 3,4-Dihydro-2(1H)-Quinazolinones through Palladium-Catalyzed Intramolecular Arylation of Ureas

3,4-Dihydro-2(1H)-quinazolinone derivatives 3-3b have been synthesized through a one-pot palladium-catalyzed heterocyclization from N-benzyl-N-(2-bromoarylmethyl)amines 1-1b and aliphatic or aromatic isocyanates 2.
