The asymmetric unit of the title compound, C25H29N3O, comprises two crystallographically independent mol­ecules. The dihedral angles between the benzene rings in the two mol­ecules are 59.7 (2) and 61.27 (18)°. The cyclo­hexene rings adopt sofa and half-chair conformations. In the crystal, mol­ecules are connected via N—H⋯O and weak C—H⋯O hydrogen bonds, forming chains along the a axis. In each mol­ecule, there is an intra­molecular N—H⋯O hydrogen bond.
