In the title compound, C₂₇H₁₈Cl₂N₂O₂, the 2-chloroquinoline and 6-chloroquinoline rings are almost planar, with maximum deviations from their mean planes of 0.072 (1) and 0.044 (1) Å, respectively, for the Cl atoms. The interplanar angle between these rings is 14.36 (5)°. The interplanar angle between the 6-chloroquinoline and phenyl rings is 66.00 (8)°. In the crystal, molecules are interlinked by weak C—H⋯O, C—H⋯π and π–π stacking [centroid–centroid distances = 3.7453 (10) and 3.7557 (9) Å] interactions.

Comment top

Quinolones have emerged as one of the important classes among chemotherapeutic drugs for treatment of various bacterial infections. The quinolones, precisely the compounds with 2-quinolone moiety, show interesting biologic activities such as antibacterial, anticancer, antiviral and cardiotonic ones (Ukita & Mizuno, 1960; Jayashree et al., 2010; Joseph et al., 2002; Xiao et al., 2001). In continuation of our previous work (Roopan et al., 2009; Khan et al., 2010), we report the structure of a new compound, 3-acetyl-2(2-chloroquinolin-3-yl)methoxy-6-chloro-4-phenylquinoline.

In the title molecule, as shown in Fig. 1, the 2-chloroquinoline (N1/C1–C9/Cl2) and 6-chloroquinoline (N2/C11—C19/Cl1) rings are almost planar, with maximal deviations from their mean planes of 0.072 (1) and of 0.044 (1) Å for Cl1 and Cl2 atoms, respectively. The interplanar angle between these rings is 14.36 (5)°. The interplanar angle between the quinoline (N2/C11—C19) and the phenyl (C20–C25) rings equals to 66.00 (8)° while the dihedral angle between the quinoline ring (N2/C11—C19) and the acetaldehyde (C26/C27/O2) group equals to 76.41 (9)°.

The molecules are linked by intermolecular C—H···O interactions (Tab. 1). The crystal structure is further stabilized by C—H···π-electron ring interactions (Tab. 1) and by π-electron···π-electron ring interactions between the pyridine ring (N2/C11– C19; its centroid is Cg1) with each of the benzene rings (C4–C9; its centroid is Cg2) and (C14–C19; its centroid is Cg3). The distances between these centroids of the respective rings are: Cg1···Cg2(1-x, 1-y, 1-z) = 3.7453 (10) Å and Cg1···Cg3 (1-x, 1-y, 2-z) = 3.7557 (9) Å.

Experimental top

To a solution of 3-acetyl-6-chloro-2-hydroxy-4-phenylquinoline (297 mg, 1 mmol) in 5 ml of dimethylsulphoxide) were added solid 2-chloro-3-chloromethylquinoline (211 mg, 1 mmol) and powder Ag₂SO₄ (30 mg, 0.1 mmol). Then the mixture was refluxed at 383 K. The reaction was completed in 20 min, having been monitored by the thin layer chromatography using petroleum ether/ethyl acetate (95:5) as an eluant. The reaction mixture was then filtered to remove the catalyst, Ag₂SO₄. The filtrate liquid was added dropwise into 50 g of crushed ice. The solution was neutralized by 20 ml of 2N HCl. The precipitate was filtered, dried and re-crystallized from 10 ml of ethanol. The solution was kept for a day after which the resulting crystals were isolated and dried. Colourless block-shaped crystals measured about 0.20 mm in each direction.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F² for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The observed criterion of F² > σ(F²) is used only for calculating -R-factor-obs 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.
