The invention relates to the field of organic chemistry - synthesis of heterocyclic compounds - derivatives 11H-indolo[2,3-C]quinoline, which can be used in the synthesis of new drugs for pharmaceutical purposes.

The invention relates to a developing method of obtaining derivatives 11H-indolo[2,3-C]quinoline of General formula I which are of interest as compounds having anticancer activity [Helissey P., Giorgi-Renault, S., Renault J., Cros, S., Chem. Pharm. Bull., 1989, 37, 675], and which can be used in the synthesis of anti-malarial drugs-analogues of the alkaloid isonipecaine [Hostyn, S., Maes B.U.W., Pieters L., Lemiere G.L.F., P. Matyus, G. Hajos, Dommisse R. A., Tetrahedron, 2005, 61, 1571].

The literature describes various approaches to the synthesis of derivatives 11H-indolo[2,3-C]quinoline. So, when boiling azides 3-phenylindolin in o-dichlorobenzene is regioselective thermal cyclization in derivatives 11H-indolo[2,3-C]quinoline [Trecourt F., F. Mongin, M. Mallet, G. Quéguiner, Synthetic Communications, 1995, 25, 4011], also these connections receive oxidative photochemical cyclization of 4-(N-phenyl)aminoquinolines in a mixture of benzene, methanol and sulphuric acid upon irradiation with ultraviolet light in the presence of traces of iodine [Dhanabal So, Sangeetha R., Mohan P.S., Tetrahedron, 2006, 62, 6258].

Another way to obtain a reaction Fisher, the interaction of 2,3-dihydro-1-H-quinoline-4-it phenylhydrazine in acetic acid in the presence of sulfuric acid [Rousseil O., Buu-Hoi N.P., Jacquignon P., Journal of the Chemical Society, 1965, 5458; He L., Chang H., Chou T., Savaraj N., Cheng C.C., European Journal of Medicinal Chemistry, 2003, 38, 101].

There are also methods based on palladium catalyzed reaction of cyclization of 4-N-(2-halogenfree)aminoquinoline [Meyers S., Rombouts G., Loones K.T.J., Coelho A., Maes B.U.W., Adv. Synth. Catal., 2008, 350, 465; Jonckers T.H.M,. Maes B.U.W., Lemiere G.L.F., Rombouts G, Pieters L., A. Haemers, Dommissea R.A., Synltett, 2003, 5, 615], leading to derived 11H-indolo[2,3-C]quinoline.

The disadvantage of these methods is either the izkuyu selectivity, or the use of expensive catalysts based on palladium.

The objective of the invention is to develop a method of obtaining derivatives 11N-indolo[2,3-C]quinoline (I, allows to expand the range of potentially biologically active substances and represents a convenient starting compound for the synthesis of analogues of the alkaloid isonipecaine.

The technical result is to introduce the desired substituents in the target product with the simultaneous formation of the quinoline nucleus.

The technical result is achieved in that in the method of obtaining derivatives 11H-indolo[2,3-C]quinoline 4-[2-(2-nitrophenyl)-1H-indol-3-yl]-but-3-EN-2-ones II [Butin A.V., Uchuskin M.G., Pilipenko A.S., Tsiunchik F.A., Cheshkov D.A., Trushkov I.V., Eur. J. Org. Chem., 2010, 920] boiled in acetic acid in the presence of carbonyl iron for 5 minutes

In the basis of the proposed method lies in the interaction of the electrophilic carbon atoms, with the nucleophilic nitrogen atom with simultaneous formation of a quinoline skeleton, described in [MacPhillamy H.B., Dziemam R.L., Lucas R.A., M.E. Kuehne, J. Am. Chem. Soc., 1958, 2172].

The technical result allows to expand the number of derivatives 11H-indolo[2,3-C]quinoline Ia-d, and thus the range of potentially biologically active compounds.
