A series of 2,3-dihydro-2-arylquinazolin-4(1H)-one derivatives were synthesized by the reaction of 2-aminobenzamide with aromatic aldehyde at room temperature catalyzed by Yb(OTf)3 in ionic liquid of [BMIm]Br. Compared to the other methods, this method has the advantages of milder reaction conditions, higher yields (85%~96%) and environmental benignity. The structures of the products were characterized by melting points, IR, 1H NMR and HRMS techniques.
