Abstract: In the title compound, C₂₃H₁₉NO, the naphthalene ring system and the cyclopent-2-enone ring exhibit planar conformations with maximum deviations of 0.034 (1) and 0.02 (1) Å, respectively. The 1,4-dihydropyridine ring adopts an envelope conformation with the C atom bearing the p-tolyl ring as the flap atom. Intermolecular N-HO hydrogen bonds and C-H interactions stabilize the crystal packing.
