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
