In the title quinazolin-4-one derivative, C24H20N2O3, both the 4-methyl­benzoate [dihedral angle = 83.90 (9)°] and 2-tolyl [87.88 (9)°] groups are almost orthogonal to the central fused ring system. These aryl groups are oriented towards the quinazolin-4-one-bound methyl group. In the crystal, mol­ecules are connected into a three-dimensional architecture by C—H⋯O, C—H⋯π and π–π [ring centroid-to-centroid separation = 3.6458 (13) Å] inter­actions.
