The mol-ecule of the title compound, C(13)H(14)N(2), is located on a crystallographic mirror plane. The aromatic rings make a dihedral angle of 3.4 (2)°. The H atoms of the methyl groups on the benzene ring are disordered over two positions; their site-occupation factors were fixed at 0.5. In the crystal, inter-molecular C-H⋯π contacts form infinite chains perpendicular to the b axis.
