Abstract

In the title compound, C(20)H(22)N(2)O(2), the asymmetric unit contains two independent half-mol-ecules, which are both completed by crystallographic inversion symmetry. The cyclo-hexane rings of both mol-ecules adopt chair conformations; the N atoms are in equatorial orientations in one mol-ecule and in axial orientations in the other. Both mol-ecules feature two intra-molecular O-H⋯N hydrogen bonds, which generate S(6) rings.
