A dry 50 ml flask was charged with benzaldehyde (10 mmol), naphthalen-2-ol (10 mmol), dimethylamine (10 mmol) (33% aq). The mixture was stirred at 100°C for 10 h and then added ethanol (15 ml), after heated under reflux for 30 minutes, the precipitate was filtrated out and washed with ethanol for 2–3 times and purified by recrystallization from dichloromethane to give the target material.
All the hydrogen atoms were calculated geometrically and with C—H distances ranging from 0.93 to 0.98 Å. Caryl—H = 0.93 Å, with Uiso(H) = 1.2Ueq(C). Cmethyl—H = 0.96 Å, with Uiso(H) = 1.5Ueq(C). O—H = 0.82 Å with Uiso(H) = 1.5Ueq(O).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Compounds derived from naphthalen-2-ol have been of great interest in organic chemistry (Szatmari & Fulop, 2004; Zhao & Sun, 2005). We report herein the crystal structure of the title compound (Fig. 1). The dihedral angle between the naphthyl ring and phenyl ring is 79.83 (6)°. Strong intramolecular O—H···N hydrogen bond [O1—H1A = 0.82 Å, H1A···N1 = 1.87 Å, O1···N1 = 2.593 (3) Å, O1—H1A···N1 = 147°] together with van der Waals interactions stabilize the molecular conformation.
