The two symmetry-independent mol-ecules in the asymmetric unit of the title compound, C(15)H(13)NO(2), differ in conformation, with the virtually planar 4-methyl-aniline (r.m.s. deviations of 0.0511 and 0.0082 Å) and piperonal groups (r.m.s. deviations of 0.0241 and 0.0486 Å) forming dihedral angles of 19.40 (5) and 42.90 (6)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions. The H atoms of the two methyl groups are disordered over two sets of sites of equal occupancy.
