In the title compound, C(21)H(22)N(2)O(4), the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å). The carboximide N atom and the five C atoms of the eth-oxy-carbonyl-methyl substituent also lie close to a common plane (r.m.s. deviation = 0.119Å), which subtends an angle of 71.06 (8)° to the naphthalamide plane. The piperidine ring adopts a chair conformation. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the a axis.
在标题化合物C₂₁H₂₂N₂O₄中，萘酰亚胺单元几乎是平面的（均方根偏差 = 0.081Å）。羧酰亚胺N原子和乙氧基羰基甲基取代基的五个C原子也靠近一个共同平面（均方根偏差 = 0.119Å），该平面与萘酰胺平面的夹角为71.06 (8)°。哌啶环呈椅式构象。在晶体中，分子间的C—H⋯O氢键将分子沿a轴连接成锯齿链。
