ABSTRACT
In the title mol-ecule, C(20)H(20)N(2)O(2), the central pyrimidine ring forms dihedral angles of 71.9â
(1) and 69.8â
(1)° with the two benzene rings. In the crystal, weak inter-molecular C-Hâ¯O hydrogen bonds link mol-ecules into centrosymmetric dimers. The crystal packing exhibits also π-π inter-actions as indicated by short distances of 3.674â
(2)â
Å between the centroids of the pyrimidine rings of neighbouring mol-ecules.
