1-[(4-Bromophenyl)(morpholin-4-yl)methyl]naphthalen-2-ol

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.
