摘要：

In the title quinazolin-4-one derivative, C 24H 20N 2O 3, 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] inter-actions.
