Source of material

Synthesis protocols toward quinoline derivatives involve the use of a Brønsted acid or Lewis acid catalyst [12–20]. Preparation of these compounds under microwave conditions have also been reported [13–15]. A solution of benzaldehyde (5 mL), phenylacetylene (8 mL) and 4-chloroanaline (6.39 g) and FeCl3 · 6H2O (0.68 mg) was heated (100 °C) overnight. The reaction mixture was cooled to room temperature and diluted with dichloromethane (250 mL). The organic solution was extracted with water (3 × 100 mL), dried over Na2SO4 and evaporated in vacuo to yield a crude product mixture. Purification was afforded with flash chromatography on silica gel (Rf 0.46; hexane:ethyl acetate = 9:1). Recrystallization from a minimum amount of dichoromethane in hexane yielded the product as faint yellow needles (2.40 g, 16%). 1H NMR (600 MHz, CDCl3) δ = 8.22–8.17 (m, 1H), 7.90 (d, J = 2.3 Hz, 1H), 7.85 (s, 1H), 7.67 (dd, J = 9.0, 2.3 Hz, 1H), 7.60–7.53 (m, 2H), 7.51–7.47 (m, 1H); 13C NMR (151 MHz, CDCl3) δ = 157.08, 148.45, 147.27, 139.22, 137.79, 132.25, 131.79, 130.49, 129.66, 129.52, 128.96, 128.88, 128.77, 127.59, 126.52, 124.53, 120.06; EIMS (70 eV) m/z 315 (M+, 100%).

Experimental details

The methyl H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95 Å and Uiso(H) = 1.5 Ueq(C).

Discussion

Quinoline is an important class of alkaloid of which the basic skeleton is present in numerous natural compounds [1, 2]. A high degree of biological activity, e.g. antimalarial, antibacterial, anticancer and antioxidant, have been attributed to these structures and has found application in the pharmaceutical industry [1–6]. Their unique spectral and photochemical properties have also found application in a variety of fields such as photolytic cleavage of DNA, electrogenerated chemiluminescence and light emitting diodes [7–11].

The asymmetric unit consists of one full molecule of the title compound (see the figure). The structure is stabilized by weak π−π and CH-π interactions. The π−π interaction is observed between the phenyl ring of the quinoline and the phenyl substituent of a neighbouring molecule with the angle between the dihedral planes of 9.9° and the centroid to centroid distance of 3.913(2) Å. The CH-π interaction is observed between the phenyl ring of the quinoline and the pyridine ring of a neighbouring molecule with a CH-centroid distance of 3.493(2) Å.
