The dihedral angle between the mean planes of the pyrimidine rings is 61.43 (6)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules, forming a two-dimensional network parallel to (001) and in combination with weak C-H⋯O hydrogen bonds, a three-dimensional network is formed. Weak C-H⋯π inter-actions and π-π inter-actions, with a centroid-centroid distance of 3.599 (2) Å are also observed.Acta crystallographica.
