In the title compound, C22H18N2O3S, the two independent mol­ecules in the asymmetric unit form a dimer via N—H⋯O hydrogen bonds. In the crystal, the mol­ecular layers can be found in the (110) plane, connected by C—H⋯π inter­actions. Atoms of the furan ring of one independent mol­ecule are disordered over two sets of sites with an occupancy ratio 0.735 (3):0.265 (3).

Structure description

The thio­phene moiety is present in a large number of bioactive mol­ecules having diverse biological activities such as anti-inflammatory (Murakami et al., 1998[Murakami, N., Takase, H., Saito, T., Iwata, K., Miura, H. & Naruse, T. (1998). Eur. J. Pharmacol. 352, 81-90.]), anti­convulsant (Kulandasamy et al., 2009[Kulandasamy, R., Adhikari, A. V. & Stables, J. P. (2009). Eur. J. Med. Chem. 44, 4376-4384.]), anti­bacterial (Lu et al., 2011[Lu, X., Wan, B., Franzblau, S. G. & You, Q. (2011). Eur. J. Med. Chem. 46, 3551-3563.]) and anti­tumor (Kaushik et al., 2012[Kaushik, N. K., Kim, H. S., Chae, Y. J., Lee, Y. N., Kwon, G., Choi, E. H. & Kim, I. T. (2012). Molecules, 17, 11456-11468.]). The quinoline ring system is one of the most commonly encountered heterocycles in medicinal chemistry (Bouraiou et al., 2007[Bouraiou, A., Belfaitah, A., Bouacida, S., Benard-Rocherulle, P. & Carboni, B. (2007). Acta Cryst. E63, o2133-o2135.]). Substituted quinolines possess diverse chemotherapeutic activities including anti­bacterial (Kidwai et al., 2000[Kidwai, M., Bhushan, K., Sapra, P., Saxena, R. & Gupta, R. (2000). Bioorg. Med. Chem. 8, 69-72.]), anti­fungal (Musiol et al., 2006[Musiol, R., Jampilek, J., Buchta, V., Silva, L., Niedbala, H., Podeszwa, B., Palka, A., Majerz-Maniecka, K., Oleksyn, B. & Polanski, J. (2006). Bioorg. Med. Chem. 14, 3592-3598.]), anti­malarial (Charris et al., 2005[Charris, J., Dominguez, J., Gamboa, N., Rodrigues, J. & Angel, J. (2005). Eur. J. Med. Chem. 40, 875-881.]; Cunico et al., 2006[Cunico, W., Cechinel, C., Bonacorso, H., Martins, M., Zanatta, N., de Souza, N., Freitas, I., Soares, R. & Krettli, A. (2006). Bioorg. Med. Chem. Lett. 16, 649-653.]) and anti­tumor (Chen et al., 2006[Chen, Y., Huang, C., Huang, Z., Tseng, C., Chang, F., Yang, S., Lin, S. & Tzeng, C. (2006). Bioorg. Med. Chem. 14, 3098-3105.]). As part of our studies in this area, we report herein the synthesis and crystal structure of the title compound.

In the asymmetric unit (Fig. 1[link]), the two independent mol­ecules A and B form a dimer via N—H⋯O hydrogen bonds (Table 1[link]). In both mol­ecules, the cyclo­hexene rings of the fused tetra­cyclic cores are puckered with QT = 0.438 (2) Å, θ = 65.0 (2)°, φ = 277.0 (3)° in A and QT = 0.481 (2) Å, θ = 111.8 (2) °, φ = 87.2 (2) ° in B. In both A and B, the mol­ecular conformation is stabilized by an N—H⋯O hydrogen bonds.

A view of mol­ecules A and B in the asymmetric unit of the title compound, with displacement ellipsoids drawn at the 50% probability level. For clarity, only the major disorder component of the furan ring in mol­ecule A is shown.

In the crystal, mol­ecular layers can be found in the (110) plane which are connected by C—H⋯π and C—H⋯N inter­actions (Fig. 2[link], Table 1[link]). There is a ππ inter­action between the N1A/C4A–C8A and C9A–C14A(−x, −y + 1, −z + 2) rings with a centroid–centroid distance of 3.7975 (10) Å.

Synthesis and crystallization

To a mixture of 3-cyano-5,6-di­hydro-4-(2-fur­yl)-benzo[h]quinoline-2(1H)-thione (10 mmol) and ethyl chloro­acetate (10 mmol) in ethanol (20 ml) containing sodium ethoxide (20 mmol) was heated under reflux for one h and then allowed to cool. The solid that formed was collected and recrystallized from ethanol. Yield: 77%; m.p. 460–461 K. IR: 3490, 3360 (NH2), 1665 (C=O) cm-1. 1H NMR (CDCl3): 8.45 (m, 1H, CH–fur­yl); 6.60 (m, 2H, 2CH–fur­yl); 7.15–7.75 (m, 4H, ArH); 5.75 (s, 2H, NH2); 4.02–4.45 (q, 2H, OCH2); 2.85 (t, 4H, CH2—CH2); 1.30–1.45 (t, 3H, CH3 of ester) p.p.m.

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.
