The title compound, C21H20BrNO2, was obtained from a condensation reaction of 4-bromobenzaldehyde, 2-naphthol and morpholine. The molecular conformation is stabilized by an intramolecular O-HN hydrogen bond, closing a six-membered ring. The dihedral angle between the naphthalene ring system and the benzene ring is 76.72 (8)°. In addition to the intramolecular hydrogen bond, the O-H groups of centrosymmetrically related molecules form short intermolecular HO contacts of 2.59 Å. These molecules are also linked by pairs of C-HO interactions, generating an R22(14) motif.
