The asymmetric unit of the title compound, C(25)H(29)N(3)O, comprises two crystallographically independent mol-ecules. The dihedral angles between the benzene rings in the two mol-ecules are 59.7 (2) and 61.27 (18)°. The cyclo-hexene rings adopt sofa and half-chair conformations. In the crystal, mol-ecules are connected via N-H⋯O and weak C-H⋯O hydrogen bonds, forming chains along the a axis. In each mol-ecule, there is an intra-molecular N-H⋯O hydrogen bond.
