The whole molecule of the title compound, C17H21NO2, is generated by twofold rotational symmetry. The N atom and the C and H atoms in position 4 of the pyridine ring lie on the twofold axis. The cyclohexene ring has a sofa conformation with the CH2 C atom adjacent to the dimethyl-substituted C atom displaced by 0.5949 (16) angstrom from the mean plane of the other five C atoms. In the crystal, weak C-H center dot center dot center dot O interactions link the molecules into chains parallel to the a axis. In addition, pi-pi stacking interactions [centroid-centroid distance = 3.8444 (7) angstrom] contribute to the stabilization of the crystal structure.
