A series of 2-(2-aminophenyl)-4-arylquinazoline derivatives (5a - j), with various 4-substituents, have been synthesized by one-pot cyclization in 66 - 79% yield by heating 2-aminoarylbenzimidamides 3a - j with isatoic anhydride (4). The high yield and simplified workup procedure, in addition to the neutral reaction conditions, are the main advantages of our approach. The structure of the product 5e
