Description
Neue 5-Phenyl-1H-1 ,5-benzodiazepin-2,4-dione Die Erfindung betrifft neue 5-Phenyl-iH-1,5-benzodiazepin-2,4-dione der allgemeinen Formel In dieser Formel bedeutet: R1 einen geraden oder verzweigten Alkylrest mit 1 - 3 Kohlenstoffatomen, der durch eine Hydroxygruppe substituiert sein kann oder den Cyclohexylrest und R2 die Trifluormethylgruppe oder ein Halogenatom.New 5-phenyl-1H-1, 5-benzodiazepine-2,4-diones The invention relates to new 5-phenyl-1H-1,5-benzodiazepine-2,4-diones of the general formula In this formula: R1 denotes a straight or branched alkyl group with 1-3 carbon atoms, which can be substituted by a hydroxyl group or the cyclohexyl group and R2 denotes the trifluoromethyl group or a halogen atom.
Die neuen Verbindungen lassen sich herstellen durch Arylierung am Stickstoffatom 5 eines 1H-1,5-benzodiazepin-2,4-dions der allgemeinen Formel worin R1 und R2 die oben angeführte Bedeutung besitzen und Y Wasserstoff, ein Alkalimetall oder eine Acylgruppe bedeutet, mit einer Verbindung der allgemeinen Formel worin X ein Halogenatom bedeutet Die Arylierung erfolgt in Gegenwart von Kupferpulver entweder unter Verwendung des Arylhalogenids der allgemeinen Formel III im Überschuß oder in polaren aprotischen Lösungsmitteln, wie zum Beispiel Dimethylformamid, Dimethylsulfoxid oder Hexamethylphosphoramid. Arbeitet man in Lösungsmitteln, so wird das Arylhalogenid lediglich in der berechneten Menge zugesetzt. Die Reaktionstemperatur ist abhängig von den jeweils eingesetzten Ausgangsstoffen und liegt im allgemeinen zwischen 90 und 1800 C. Geht man von solchen Verbindungen der allgemeinen Formel II aus, worin Y ein Wasserstoffatom oder eine Acylgruppe bedeutet, so ist der Zusatz einer geeigneten organischen oder anorganischen Base, beispielsweise eines Alkalicarbonats oder -bicarbonats oder vorzugsweise eines Alkaliacetats in molaren Mengen oder im Überschuß zur Bindung des entstehenden Halogenwasserstoffs notwendig.The new compounds can be prepared by arylation on the nitrogen atom 5 of a 1H-1,5-benzodiazepine-2,4-dione of the general formula where R1 and R2 are as defined above and Y is hydrogen, an alkali metal or an acyl group, with a compound of the general formula in which X is a halogen atom. The arylation is carried out in the presence of copper powder either using an excess of the aryl halide of the general formula III or in polar aprotic solvents, such as dimethylformamide, dimethyl sulfoxide or hexamethylphosphoramide. If you work in solvents, the aryl halide is only added in the calculated amount. The reaction temperature depends on the starting materials used in each case and is generally between 90 and 1800 C. If one starts out from compounds of the general formula II in which Y is a hydrogen atom or an acyl group, then the addition of a suitable organic or inorganic base, For example, an alkali metal carbonate or bicarbonate or preferably an alkali metal acetate in molar amounts or in excess is necessary to bind the hydrogen halide formed.
Die als Ausgangsstoffe verwendeten 1H-1,5-Benzodiazepin-2,4-dione der allgemeinen Formel II sind neu. Sie können beispielsweise erhalten werden durch Umsetzung eines entsprechend substituierten 2-Nitroanilins mit einem Malonsäuremonoalkylesterhalogenid, Reduktion des gebildeten 2-Nitromalonsäurealkylesteranilids und Cyclisierung des 2-Aminomalonsäureäthylesteranilids nach folgendem Reaktionsschema: Die neuen Verbindungen der allgemeinen Formel I besitzen starke psychosedative und antikonvulsive Eigenschaften bei teilweise außerordentlich geringer Toxizität.The 1H-1,5-benzodiazepine-2,4-diones of the general formula II used as starting materials are new. They can be obtained, for example, by reacting a correspondingly substituted 2-nitroaniline with a malonic acid monoalkyl ester halide, reducing the 2-nitromalonic acid alkyl ester anilide formed and cyclizing the 2-aminomalonic acid ethyl ester anilide according to the following reaction scheme: The new compounds of general formula I have strong psychosedative and anticonvulsant properties with, in some cases, extremely low toxicity.
Als Dosis für die Anwendung der neuen Verbindungen der Formel I werden 0,5 bis 50 vorzugsweise 1 - 25 mg als Einzeldosis und 5 - 150 mg als Tagesodsis vorgeschlagen.As a dose for the application of the new compounds of the formula I will be 0.5 to 50, preferably 1 to 25 mg as a single dose and 5 to 150 mg as daily deathsis suggested.
