In the title molecule, C 20 H 22 N 2 O, the pyridine heterocycle has an envelope conformation. The crystal packing is stabilized by intermolecular N-HÁ Á ÁO hydrogen bonds, which link the molecules into chains along the [110] direction.
Molecules of the title compound, C 27 H 23 N 3 O 2 , contain four rings that are not coplanar and the pyrimidine ring is slightly distorted from planarity. The dihedral angles between pairs of benzene rings are 88.6 (1), 88.6 (1) and 62.9 (1) . The three benzene rings form dihedral angles of 55.3 (1
