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—H⋯N 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 H⋯O contacts of 2.59 Å. These molecules are also linked by pairs of C—H⋯O interactions, generating an R22(14) motif.
