Abstract: In the title compound, C19H17NO2, the dihedral angle between the benzene ring and the naphthalene ring system is 9.72 (5)°, while the torsion angle of the C-N-C-C bridging group is 179.24 (17)°. The methyl group of the 1-phenylethanol moiety is disordered over two positions with a refined occupancy ratio of 0.775 (5):0.225 (5). The molecular conformation is stabilized by an intramolecular N-H...O hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked by O-H...O hydrogen bonds, forming zigzag chains propagating along the c-axis direction. Neighbouring chains are linked via C-H...O interactions, forming a two-dimensional slab-like network parallel to the bc plane.
