The asymmetric unit of the title compound, C(22)H(18)N(2)O(2), contains two independent mol-ecules, which differ in the orientations of the benzyl groups with respect to the planar (r.m.s. deviations of 0.031 and 0.020 Å) quinazoline-2,4-dione skeletons [dihedral angles of 73.97 (4) and 70.07 (4)° in the first mol-ecule and 75.63 (4) and 63.52 (3)° in the second]. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π interactions and aromatic π-π stacking inter-actions [centroid-centroid distance = 3.735 (2) Å].
