There are two mol-ecules in the asymmetric unit of the title compound, C(19)H(12)N(4), with dihedral angles of 2.41 (10) and 10.53 (12)° between the fused ring system and the pendant phenyl ring. In the crystal, mol-ecules are linked into chains by N-H⋯N hydrogen bonds and aromatic π-π stacking inter-actions [shortest centroid-centroid distance = 3.6176 (16) Å] complete the structure.
