In the title mol-ecule, C(21)H(24)N(2)O(4), the piperidine ring adopts a distorted boat conformation with the ethyl substituent in the axial position. The dihedral angle between the two benzene rings is 70.25 (9)°. An intra-molecular C-H⋯O inter-action is observed. In the crystal, mol-ecules are linked into a chain along the c axis by C-H⋯O hydrogen bonds and the chains are linked via weak C-H⋯π inter-actions.
在标题分子C(21)H(24)N(2)O(4)中，哌啶环呈扭曲的船式构象，乙基取代基处于轴向位置。两个苯环之间的二面角为70.25 (9)°。观察到分子内存在C—H⋯O相互作用。在晶体中，分子通过C—H⋯O氢键沿c轴连接成链，且这些链通过弱C—H⋯π相互作用相连。
