Methyl 2,6-diphenyl-1-p-tolyl-4-(p-tolyl-amino)-1,2,5,6-tetra-hydro-pyridine-3-carboxyl-ate.

In the title compound, C(33)H(32)N(2)O(2), the tetra-hydro-pyridine ring adopts a boat conformation with the carbonyl group in an s-cis conformation with respect to the C=C bond of the six-membered tetra-hydro-pyridine ring. The mol-ecular conformation is stabilized by intra-molecular N-H⋯O, C-H⋯O and C-H⋯π inter-actions. Formation of centrosymmetric head-to-head dimers is observed through pairwise inter-molecular N-H⋯O hydrogen bonds. Additional weak C-H⋯O and C-H⋯π inter-actions stabilize the three-dimensional mol-ecular assembly.
