The asymmetric unit of the title compound, C(29)H(29)N(3)O(3), contains two mol-ecules, which exist in their enamine-keto form, being stabilized by strong intra-molecular N-H⋯O hydrogen bonds, which generate S(6) loops. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains, which are further linked by weak C-H⋯π inter-actions, forming a two-dimensional network.
