The asymmetric unit of the title compound, C(17)H(23)NO(2), consists of two crystallographically independent mol-ecules (A and B). The cyclo-hexene rings in both mol-ecules adopt an envelope conformation. In the crystal, independent mol-ecules, A and B, are each linked by inter-molecular bifurcated (N,O)-H⋯O hydrogen bonds, generating R(2) (1)(7) ring motifs and forming infinite chains along the b axis.
