Abstract
The title compound, C22H20N2O2, was synthesized via a multicomponent reaction using naphthalen-2-ol, morpholine and 4-formylbenzonitrile. The dihedral angle between the naphthalene ring system and the benzene ring is 81.25 (10)°. The morpholine ring adopts a chair conformation. The molecular conformation is stabilized by intramolecular O—H⋯N and C—H⋯O hydrogen bonds. In the crystal, intermolecular C—H⋯N hydrogen bonds link molecules into helical chains running parallel to the c axis.
