(Received 24 March 2010; accepted 26 March 2010; online 31 March 2010)

In the title compound, C17H15ClN2O, the quinoline ring system is nearly planar, with a maximum deviation from the mean plane of 0.074 (2) Å, and makes a dihedral angle of 81.03 (7)° with the pyridone ring. The crystal packing is stabilized by ππ stacking inter­actions between the pyridone and benzene rings of the quinoline ring system [centroid–centroid distance = 3.6754 (10) Å]. Furthermore, weak inter­molecular C—H⋯O hydrogen bonding links mol­ecules into supra­molecular chains along [001].

Comment top

Compounds found in nature display a wide range of diversity in terms of their structures and physical and biological properties. Several alkaloid analogues of natural or synthetic anticancer agents (Roopan & Khan, 2009) are well known, and have attracted considerable interest because of their significant activity. Particularly, five and six membered heterocyclic compounds containing one or two hetero atoms fused to a quinoline ring are found in natural products. The search for new anticancer drugs from nature continues to be a fruitful activity, as evidenced by the successes of natural products as pharmaceutical agents. Nitrogen containing heterocyclic compounds, recognized pharmacophores has received great attention in drug discovery and lead optimization. The chemistry of N-alkylation has recently received much attention due to their usefulness as building blocks in organic synthesis (Roopan et al., 2010). On the basis of the interesting structures and biological activities exhibited by several heterocyclic systems possessing quinoline and pyridone nucleus, we have synthesized a quinoline coupled pyridone, i.e., 1-[(2-chloroquinolin-3yl)-methyl]-pyridine-2(1H)-one.

In the title molecule, Fig.1., the quinoline unit is nearly planar, with maximum deviations from the mean plane of -0.074 (2) Å for C2, -0.061 (2) Å for C6 and 0.059 (1) Å for N1 and 0.049 (2) Å for C4. The dihedral angle between the pyridine ring and the quinoline fused-ring system is 81.03 (7)°. Molecular conformation is stabilized by the intra molecular C—H···N and C—H···Cl interactions, forming a 5-membered ring. The crystal structure shows the presence of intermolecular π-π interactions between the pyridone (N2/C11–C15) and benzene (C4–C9) rings of the quinoline ring system, with the Cg2···Cg3(x, 1/2-y, 1/2+z) distance of 3.6754 (10) Å [Cg2 and Cg3 are the centroids of the N2/C11–C15 pyridone and C4–C9 benzene rings, respectively]. The molecular packing is further stabilized by weak intermolecular C—H···O interactions (Table1, Fig. 2), forming chains in the [001] direction.

Experimental top

To a mixed well solution of 2-pyridone (95 mg, 1 mmol, in 2 ml of DMF), KOtBu (112 mg, 1 mmol in 10 ml of THF) and 2-chloro-3-(chloromethyl)-7,8-dimethylquinoline (240 mg, 1 mmol) were added and the resulting mixture was refluxed at 343 K for 1 h. After the completion of the reaction, cooled and removed the excess of solvent under reduced pressure. Crushed ice was mixed with the residue. White solid was formed, filtered and dried, purified by column chromatography using hexane and ethylacetate as the eluant. Crystals of suitable quality were grown by solvent evaporation from a solution of the compound in chloroform.

Refinement top

All H atoms were positioned geometrically and were treated as riding on their parent C atoms, with C—H = 0.93-0.97 Å and Uiso(H) = 1.2 or 1.5Ueq(C).

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.
