    The invention relates to the production of new indole derivatives, which can be used in the pharmaceutical industry. A known method of producing ethers by alkylation with halogen-containing compounds. The purpose of the invention is to obtain new compounds with valuable pharmacological properties. The goal is achieved by the proposed method of obtaining indole derivatives of the general formula p3% Vl - C - O ilH.V 1 Kf - hydrogen, unbranched or branched C, C4: C5, Cj alkyl or C alkenyl, Ra - CJ-C alkyl, which may be substituted with phenyl, fe, NIL, substituted or unsubstituted by halogen / methoxy, amino, nitro or acetamido, pyridyl or R and R together -C: j 5 alkylene, alkyl substituted or unsubstituted with phenyl, unsubstituted or substituted by methoxy, trifluoromethyl group or halogen atom, phenyl, unsubstituted or substituted - m Ethyl, methoxy, trifluoromethyl group, or by a halogen atom, pyridyl or quinolyl, R - cyano, carboxy 1 or C - C -. alkoxy (carbonyl aminocarbonyl unsubstituted or substituted by C alkyls, allyl or cyclohexyl, morpholinothioMorpholino or piperidinecarbonyl group} Yab is hydrogen, methyl or benzyl; Rfe is hydrogen or methyl or their salts, if carboxyl, means that oxindol is common formulas where they have the indicated values or its alkali metal salt, are reacted with a compound of the general formula X-i-Bjt UHj where I is halogen; has the indicated values. The reaction is carried out preferably in a solvent, for example acetone, methyl ethyl ketone, toluene, dimethylformamide, triamide hexamethylphosphoric acid or glycol dimethyl ether in the presence of a base, such as potassium carbonate or sodium hydride, if necessary in the presence of a phase conversion catalyst, such as a quaternary ammonium salt, or for example, 18-crown-b ILO tetrabutyl-chlorammonium, 0-200 ° C, preferably, however, at temperatures between room temperature and the boiling point of the solvent, for example at 20-100 ° C. The reaction is also carried out in the melt. If a compound of general formula T is prepared, where I, besides the carboxyl and oxymethyl groups, has the indicated value, then it is converted by hydrolysis into the corresponding compound of general formula 1, where is the carboxyl group.
    The resulting compounds of general formula I, where the. Is a carboxyl group, can be converted S to their physiological and tolerable salts with inorganic or organic bases, or into their physiologically tolerable salts with inorganic or organic acids. At the same time, for example, sodium hydroxide, potassium hydroxide or cyclohexylamine are suitable as bases, and 10 as hydrochloric, hydrobromic, sulfuric, phosphoric, lactic, liaronic, tartaric, maleic or fumaric acids as acids.
