title: Methyl 6-oxo-4-phenyl-2-[(Z)-2-(pyridin-2-yl)ethen-yl]-1,4,5,6-tetra-hydro-pyridine-3-carboxyl-ate.
abstract: In the title mol-ecule, C20H18N2O3, an intra-molecular N-H⋯O hydrogen bond leads to a cis conformation of the pyridinyl-vinyl fragment. The phenyl and pyridine rings are inclined to one another by 77.3 (1) °. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. The dimers are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional structure.
