Abstract
The title compound, C21H20BrNO2, was obtained via a one-pot synthesis from the reaction of 4-bromobenzaldehyde, 2-naphthol and morpholine. In the asymmetric unit, there are four molecules with similar structures. The morpholine ring adopts a chair conformation, and the hydroxy group links with the morpholine via an intramolecular O—H⋯N hydrogen bond. The bromophenyl ring is approximately perpendicular to the mean pane of the naphthalene system at dihedral angles of 76.7 (3), 81.4 (3), 79.7 (3) and 84.5 (3)° in the four independent molecules. Weak C—H⋯O hydrogen bonds are observed in the crystal.
