In the title compound, C24H18Cl4N4, the pyrimidine ring makes dihedral angles of 19.1 (2), 4.1 (2) and 67.5 (2)°, respectively, with phenyl and two benzene rings, and the mol-ecular conformation is stabilized by an intra-molecular N-H⋯N hydrogen bond closing a six-membered ring with an S(6) motif. In the crystal, a pair of inter-molecular N-H⋯N hydrogen bonds connect two mol-ecules, forming inversion dimers with R2(2)(12) motifs. C-H⋯π inter-actions links the dimers into a chain running along the a-axis direction. There are also π-π stacking inter-actions [centroid-centroid distance = 3.666 (4) Å] between the benzene rings of adjacent chains.
