Abstract: In the title molecule, C20H18N2O3, an intramolecular N-HO 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, molecules are linked via pairs of C-HO hydrogen bonds, forming inversion dimers. The dimers are linked by C-HO hydrogen bonds and C-H interactions, forming a three-dimensional structure.
