Process for the preparation of carbostyril derivatives of the general formula in which a vinylene group optionally substituted by a methyl group or the ethylene group, a straight-chain or branched alkylene group with 2 to 6 carbon atoms, a straight-chain or branched hydroxyalkylene group with 3 to 6 carbon atoms or a xylylene group, the number 0, 1 or 2, | R1 is a hydrogen atom or an alkyl group with 1 to 3 carbon atoms, R2 a cycloalkyl group with 3 to 6 carbon atoms, an aryl group with 6 to 10 carbon atoms, an aralkyl group with 7 to 11 carbon atoms, a heteroaryl group containing one nitrogen atom and / or one oxygen or sulfur atom or two nitrogen atoms with 4 to 9 carbon atoms or a heteroaralkyl group with 5 to 10 carbon atoms, the aromatic nuclei listed above by an alkyl group with 1 to 4 carbon atoms, by a hydroxy, methoxy, amino, acetylamino, nitro, carboxyl, cyclohexyl -, phenyl group or a halogen atom and additionally the Above-mentioned monosubstituted phenyl group by alkyl groups with 1 to 4 carbon atoms and / or halogen atoms can be mono- or disubstituted (whereby the substituents of the phenyl nucleus can be the same or different), the 1,2,4-triazolyl-, triphenylmethyl-, 4, 5-bis (p-chlorophenyl) oxazol-2-yl, N-methyl-cyclohexylaminocarbonylmethyl or amino-iminomethyl group or an alkyl group with 1 to 6 carbon atoms, if either mm the number 1 or DD is a straight-chain or branched hydroxyalkylene group with 3 represents 3 to 6 carbon atoms or a xylylene group, R3 and R4, which can be identical or different, represent hydrogen or halogen atoms, alkyl groups with 1 to 4 carbon atoms, amino, acetylamino or nitro groups.
Die Verbindungen der obigen allgemeinen Formel I weisen wertvolle pharmakologische Eigenschaften auf, neben einer positiv inotropen Wirkung insbesondere antithrombotische Eigenschaften.The compounds of the above general formula I have valuable pharmacological properties, in addition to a positive inotropic effect in particular antithrombotic properties.
Es wurde nun gefunden, daß sich die Carbostyrile der allgemeinen Formel I auch nach folgenden Verfahren herstellen lassen: a) Cyclisierung einer gegebenenfalls im Reaktionsgemisch gebildeten Verbindung der allgemeinen Formel in der D, W, R1 bis R4 und m wie eingangs definiert sind und Z eine nukleophile Austrittsgruppe wie die Hydroxygruppe, ein Halogenatom, eine Alkoxy-, Aryloxy- oder Aralkoxygruppe bedeutet.It has now been found that the carbostyrils of the general formula I can also be prepared by the following processes: a) Cyclization of a compound of the general formula which may be formed in the reaction mixture in which D, W, R1 to R4 and m are as defined at the outset and Z is a nucleophilic leaving group such as the hydroxy group, a halogen atom, an alkoxy, aryloxy or aralkoxy group.
Die Cyclisierung wird vorzugsweise in Gegenwart eines Kondensationsmittels wie Schwefelsäure, konz. Salzsäure, phosphorsäure oder Thionylchlorid zweckmäßigerweise in einem Lösungsmittel wie Eisessig, Tetrahydrofuran, Dioxan, Chloroform, Toluol, Äthanol oder in einem Überschuß des verwendeten Kondensationsmittels bei erhöhten Temperaturen, z.B. bei Temperaturen zwischen 50 und 2000C, vorzugsweise jedoch bei Temperaturen zwischen 80 und 1500C, durchgeführt. Die Umsetzung kann jedoch auch ohne Lösungsmittel und/oder Kondensationsmittel durchgeführt werden.The cyclization is preferably carried out in the presence of a condensing agent like sulfuric acid, conc. Hydrochloric acid, phosphoric acid or thionyl chloride are expedient in a solvent such as glacial acetic acid, tetrahydrofuran, dioxane, chloroform, toluene, Ethanol or in an excess of the condensing agent used at elevated levels Temperatures, e.g. at temperatures between 50 and 2000C, but preferably at Temperatures between 80 and 1500C. However, the implementation can also be carried out without solvents and / or condensing agents.
Hierbei ist es nicht erforderlich, eine als Ausgangsstoff verwendete Verbindung der allgemeinen Formel II zu isolierten.It is not necessary here to use one as a starting material To isolate compound of general formula II.
Diese kann vielmehr aus der entsprechenden Nitroverbindung in situ hergestellt werden, z.B. durch Reduktion der Nitrogruppe mit Wasserstoff in Gegenwart eines Hydrierungskatalysators wie Palladium/Kohle, Palladium/Calciumcarbonat oder Palladium/Calciumkarbonat + Bleiacetat (Lindlar-Katalysator), durch Reduktion mit Metallen wie Eisen, Zinn oder Zink in Gegenwart einer Säure, durch Reduktion mit Salzen wie Eisen-(II)-sulfat, Zinn-(II)-chlorid, Chrom-(II)-chlorid oder Natriumdithionit oder durch Reduktion mit Hydrazin in Gegenwart von Raney-Nickel. Rather, this can be obtained from the corresponding nitro compound in situ can be produced, e.g. by reducing the nitro group with hydrogen in the presence a hydrogenation catalyst such as palladium / carbon, palladium / calcium carbonate or Palladium / calcium carbonate + lead acetate (Lindlar catalyst), through reduction with Metals such as iron, tin or zinc in the presence of an acid, through reduction with Salts such as iron (II) sulfate, tin (II) chloride, chromium (II) chloride or sodium dithionite or by reduction with hydrazine in the presence of Raney nickel.
Bedeutet in einer entsprechenden Nitroverbindung m die Zahl 1, so erfolgt die Reduktion der Nitrogruppe zweckt mäßigerweise mit der äquivalenten Menge des erforderlichen Reduktionsmittels, z.B. mit einem Metallsalz wie Eisen-(II)-sulfat, Zinn-(II)-chlorid, Chrom-(II)-chlorid oder Natriumdithionit, oder mit Wasserstoff in Gegenwart eines desaktivierten Hydrierungskatalysators, z.B. in Gegenwart von i Palladium/Calciumkarbonat + Bleiacetat. Führt man beispielsweise die Reduktion in Gegenwart von Palladium/Kohle durch, so wird die Sulfoxydgruppe teilweise mitreduziert.
