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) Å from the mean plane of the other five C atoms. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into chains parallel to the a axis. In addition, π-π stacking inter-actions [centroid-centroid distance = 3.8444 (7) Å] contribute to the stabilization of the crystal structure.
标题化合物C17H21NO2的整个分子由二重旋转对称性产生。吡啶环4位的N原子以及C原子和H原子位于二重轴上。环己烯环具有沙发式构象，与二甲基取代的C原子相邻的CH2 C原子偏离其他五个C原子的平均平面0.5949 (16) Å。在晶体中，弱的C-H⋯O相互作用将分子连接成平行于a轴的链。此外，π-π堆积相互作用[质心-质心距离 = 3.8444 (7) Å]有助于晶体结构的稳定。
