In the title compound, C15H12ClN3O, the quinoline ring system is essentially planar, with a maximum deviation of 0.017 (1) Å. The crystal packing is stabilized by π–π stacking interactions between the quinoline rings of adjacent molecule, with a centroid–centroid distance of 3.5913 (8) Å. A weak C—H⋯π contact is also observed between molecules.

To a mixed well solution of 4(3H)-pyrimidone (96 mg, 1 mmol, in 5 ml DMSO), NaH (25 mg, 1 mmol) and 2-chloro-3-(chloromethyl)-8-methylquinoline (225 mg, 1 mmol) were added and the resulting mixture was refluxed for 1 h. Completion of the reaction was monitored by TLC. 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
using hexane and ethylacetate as the eluant. The low polar compound was subjected into crystallization by solvent evaporation from a solution of the compound in chloroform.All H atoms were placed in geometrically idealised positions and constrained to ride on their parent atoms (C—H = 0.93, 0.96 and 0.97 Å) and Uiso(H) values were taken to be equal to 1.2 Ueq(C) for aromatic and methylene H atoms and 1.5Ueq(C) for methyl H atoms.
Alkylating agents have been studied extensively both for their biological effects and for their mode of action (Singer et al., 1986). There have been over the past 25 years a veritable deluge of reviews, often focusing on a single aspect or agent or adduct. Direct alkylation of oxygens in pyrimidine
under physiological conditions, has been known only since the middle 1970s. The pyrimidine analogues (Svenstrup et al., 2008) such as naturally occurring azacamptothecin based molecule have been focused of great interest by reason of their diversified biological activities. Thus, modifications of biologically active azacamptothecin synthons may lead to achieve the highly expected effective drugs. In connection with the program of synthesis and regioselective alkylation of 4(3H)-pyrimidone (Roopan et al., 2010), we report herein the synthesis of 2-chloro-8-methyl-3-[(pyrimidin-4-yloxy)methyl]quinoline.In the molecule of the title compound, Fig. 1, bond lengths and angles are in normal ranges (Allen et al., 1987). The quinoline ring system (N1/C1–C9) is essentially planar, with a maximum deviation of -0.017 (1) Å for atom C1. The quinoline system (N1/C1–C9) makes a dihedral angle of 4.99 (6)° with the piyrimidone ring (N2/N3/C11–C14).
In the title molecule, there is a weak intramolecular C—H···O interaction, generating an S(5) graph-set motif (Bernstein et al., 1995) (Table 1). The crystal packing is stabilized by π-π stacking interactions between the benzene rings of the quinoline ring system of the molecules related by the symmetry operator (1-x, 1-y, -z) [centroid-to-centroid distance = 3.5913 (8) Å]. In addition, a weak C—H···π contact is also observed between molecules (Table 1). The packing diagram viewing down the b-axis is shown in Fig. 2.

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. |

Alkylating agents have been studied extensively both for their biological effects and for their mode of action (Singer et al., 1986). There have been over the past 25 years a veritable deluge of reviews, often focusing on a single aspect or agent or adduct. Direct alkylation of oxygens in pyrimidine nucleosides, under physiological conditions, has been known only since the middle 1970s. The pyrimidine analogues (Svenstrup et al., 2008) such as naturally occurring azacamptothecin based molecule have been focused of great interest by reason of their diversified biological activities. Thus, modifications of biologically active azacamptothecin synthons may lead to achieve the highly expected effective drugs. In connection with the program of synthesis and regioselective alkylation of 4(3H)-pyrimidone (Roopan et al., 2010), we report herein the synthesis of 2-chloro-8-methyl-3-[(pyrimidin-4-yloxy)methyl]quinoline.
In the molecule of the title compound, Fig. 1, bond lengths and angles are in normal ranges (Allen et al., 1987). The quinoline ring system (N1/C1–C9) is essentially planar, with a maximum deviation of -0.017 (1) Å for atom C1. The quinoline system (N1/C1–C9) makes a dihedral angle of 4.99 (6)° with the piyrimidone ring (N2/N3/C11–C14).
In the title molecule, there is a weak intramolecular C—H···O interaction, generating an S(5) graph-set motif (Bernstein et al., 1995) (Table 1). The crystal packing is stabilized by π-π stacking interactions between the benzene rings of the quinoline ring system of the molecules related by the symmetry operator (1-x, 1-y, -z) [centroid-to-centroid distance = 3.5913 (8) Å]. In addition, a weak C—H···π contact is also observed between molecules (Table 1). The packing diagram viewing down the b-axis is shown in Fig. 2.
