A combinatorial synthesis of 3-arylideneaminoquinazolin-4(1H)-one derivatives is described by a reaction of 2-aminobenzohydrazides with two equivalents of aldehydes or ketones in ionicliquidscatalyzed by iodine. Controlling the reaction temperature or reducing the activity of the substrates, respectively, the intermediate products of hydrazones were obtained first, and then they were applied to react
