In the crystal of the title compound, C 17 H 16 N 2 , molecules are linked by C—H...N hydrogen bonds, forming rings of graph-set motifs R 2 1 (6) and R 2 2 (10). The title molecule is close to planar, with a dihedral angle between the aromatic rings of 0.6 (1)°. Torsion angles confirm a conformational trans structure.
