(Received 2 September 2008; accepted 5 September 2008; online 13 September 2008)

In the title compound, C22H23NO, the dihedral angle between the naphthyl ring system and the benzene ring is 73.32 (6)°. An intra­molecular O—H⋯N hydrogen bond stabilizes the mol­ecular conformation. In the crystal structure, mol­ecules are linked by C—H⋯π inter­actions, resulting in zigzag chains parallel to the [10[\overline{1}]] direction.

Comment top

Compounds derived from naphthalen-2-ol have been of great interest in organic chemistry (Szatmari & Fulop, 2004; Zhao & Sun, 2005). We report here the crystal structure of the title compound (Fig. 1).

Bond lengths and angles in the title compound have normal values. The dihedral angle between the naphthyl and phenyl rings is 73.32 (6)°. The pyrrolidine ring adopts a twist conformation, as indicated by the puckering parameters (q2 = 0.401 (2) Å and ϕ = 169.2 (4)°; Cremer & Pople, 1975) and the small value of the displacement asymmetry parameter (ΔC2(C14) = 0.0301 (10)°; Nardelli, 1983). The molecular conformation is stabilized by a strong intramolecular O—H···N hydrogen bond (Table 1). In the crystal packing, molecules are linked through C—H···π interactions (Table 1) to form zig zag chains running along the [1 0 -1] direction.

Experimental top

A dry 50 ml flask was charged with benzaldehyde (10 mmol), naphthalen-2-ol (10 mmol), and pyrrolidine (10 mmol). The mixture was stirred at 100°C for 10 h then ethanol (15 ml) was added. After heating under reflux for 30 minutes, the precipitate was filtrated off and washed 3 times with ethanol to give the title compound. Single crystals suitable for X-ray analysis were obtained by slow evaporation of a dichloromethane solution.

Refinement top

All hydrogen atoms were calculated geometrically, with C—H = 0.93-0.98 Å, O—H= 0.82 Å, and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.2Ueq(C, O) for methyl and hydroxy hydrogen atoms.

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.
