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

The title compound, C 21H 20BrNO 2, was obtained via a one-pot synthesis from the reaction of 4-bromo-benzaldehyde, 2-naphthol and morpholine. In the asymmetric unit, there are four mol-ecules with similar structures. The morpholine ring adopts a chair conformation, and the hy-droxy group links with the morpholine via an intra-molecular O - H⋯N hydrogen bond. The bromo-phenyl 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 mol-ecules. Weak C - H⋯O hydrogen bonds are observed in the crystal.
