8-Benz-yloxy-2-methyl-3-(2-methyl-phenyl)quinazolin-4(3H)-one.

ABSTRACT: In the title methaqua-lone analogue, C(23)H(20)N(2)O(2), the planes of the terminal aromatic rings [dihedral angle between them = 64.52 (7)°] approximately face the fused-ring methyl group and both are twisted with respect to the pyrimidine plane (r.m.s. deviation = 0.028 Å), forming dihedral angles of 86.9 (3) (with the 2-tolyl ring) and 65.57 (7)°. The 2-tolyl residue is disordered over two almost coplanar but opposite orientations with the major component having a site-occupancy factor of 0.893 (3). The three-dimensional crystal packing is consolidated by C-H⋯O, C-H⋯π and π-π [2-tol-yl-2-tolyl centroid-centroid distance = 3.8099 (6) Å] inter-actions.
