The title compound, C15H12N4O, was synthesized by a standard Suzuki cross-coupling reaction. The terminal pyrim-idine rings are rotated at dihedral angles of 12.06 (4) and -13.13 (4)° with respect to the central benzene ring. In the crystal, the mol-ecules are connected by two kinds of C-H⋯N hydrogen bonds, forming zigzag chains along the c axis. Weak π-π inter-actions between the benzene and one of the pyrimidine rings are also found and stack the mol-ecules along the b axis [centroid-centroid distance = 4.112 (3) Å].
