Abstract
In the title compound, C21H22N2O4, the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å). The carboximide N atom and the five C atoms of the ethoxycarbonylmethyl 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, intermolecular C—H⋯O hydrogen bonds link the molecules into zigzag chains along the a axis.
