Deskripsi
In the title methaqualone analogue, C23H20N2O2, 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-tolyl–2-tolyl centroid–centroid distance = 3.8099 (6) Å] interactions.
