In the title compound, C20H20N2O2, the quinoline ring system makes dihedral angles of 81.05 (4) and 61.16 (5)° with the mean planes of the benzene and morpholine rings, respectively; the mean planes of the latter two rings make a dihedral angle of 83.59 (4)°. In the crystal, pairs of O—H⋯N hydrogen bonds link neighbouring mol­ecules related by a twofold rotation axis, generating R22(10) motifs.

Comment top

Quinoline analogues have been reported to display promising biological activities such as antimicrobial, anti–inflammatoty, antileishmanial, antituberculosis, antimalarial, cytotoxicity and HIV–1 integrase inhibitors (Thakur et al., 2010). In continuation of our efforts to develop quinoline derivatives with a new structure–activity relationalship, herein, we report the synthesis and structure determination of the title compound.

In the title molecule (Fig.1), the benzene(C11—C16) and morpholine (N2/O2/C17—C20) rings make dihedral angles of 81.05 (4)° and 61.16 (5)° with the quinoline ring system, respectively. The dihedral angle between the benzene and morpholine rings is 83.59 (4)°. The title molecule is chiral with a chiral centre at C10. The morpholine ring adopts an almost perfect normal chair conformation having total puckering amplitude, QT of 0.5876 (15) Å, θ = 3.34 (14)° and ϕ = 176 (3)° (Cremer & Pople, 1975). The sum of the bond angles around N2 [329.13 (32)°] indicates a pyramidal geometry. The N2 atom deviates by 0.2613 (10) Å from the least–squares plane passing through atoms C17—C20.

In the crystal packing (Fig. 2), intermolecular O—H···N hydrogen bonds (Table 1) link the neighbouring molecules and generate an R22(10) motif (Bernstein et al., 1995).

At x=0.0, y= 0.0, z= 0.321 the crystal contains small void with the solvent accessible volume of 33 Å3.

Experimental top

8-Hydroxyquinoline (14.5 g; 0.1 mol) was dissolved in 25 ml of acetone and placed in a 250 ml beaker with constant stirring at 305 K for 1/2 h, then benzaldehyde (10.6 g; 0.1 mol) followed by morpholine (8.71 g; 0.1 mol) was added and the mixture was stirred well. The reaction mixture was left for 48 h and the resulting precipitate was collected by filtration and washed with cold water to give pale brown solid (m.p. 338 K) was obtained (yield: 70%). Single crystals suitable for X-ray diffraction were obtained from ethanol.

Refinement top

H1A of the OH group was located in an electron difference map and refined freely. Remaining H atoms were positioned geomentrically and allowed to ride on their parent atoms, with C—H = 0.95–1.00 Å and Uiso(H) = 1.2 times Ueq(C).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
