Bisher waren keine Isoxazol-Derivate mit einer substituierten oder unsubstituierten Alkylaminogrüppe am Isoxazolring bekannt. Es wurde festgestellt, daß die erfindungsgemäß erhältlichen Isoxazol-Derivate verschiedene pharmakologische Wirksamkeiten aufweisen. . . . ■So far there have been no isoxazole derivatives with a substituted or unsubstituted alkylamino group known on the isoxazole ring. It was found that the isoxazole derivatives obtainable according to the invention have different pharmacological activities. . . . ■
Die Halogenalkylisoxazolausgangsverbindungen der allgemeinen Formel III oder IV können mit Hilfe üblicher Verfahren erhalten werden.The haloalkylisoxazole starting compounds of the general formula III or IV can be prepared with the aid conventional procedures can be obtained.
Gemäß dem erfindungsgemäßen Verfahren kann die Reaktion so durchgeführt werden, daß man die Halogenalkylisoxazolverbindung der allgemeinen Formel III oder IV mit dem Amin der allgemeinen Formel. V in einem inerten Lösungsmittel innerhalb eines weiten Temperaturbereiches und, falls notwendig, in Gegenwart einer basischen Substanz zur Säurebindung umsetzt.According to the process of the invention, the reaction can be carried out so that the Haloalkylisoxazole compound of the general formula III or IV with the amine of the general formula. V in an inert solvent within a wide temperature range and, if necessary, in Reacts the presence of a basic substance for acid binding.
Als Reaktionsmedium verwendbare inerte Lösungsmittel kommen in Betracht: Wasser, wäßrige Alkanole, Alkanole, Benzol, Toluol, Xylol, Phenol und Nitrobenzol. Als Beispiele basischer Substanzen können erwähnt werden: organische Basen, wie Pyridinbasen, z. B. Pyridin, Picolin, Butidin, Collidin, und aliphatische Amine, z. B. Dimethylamin. Diethylamin, Triäthylamin, und anorganische Basen, z.B. Alkalimetallcarbonate, z. B. Natriumcarbonat, Kaliumcarbonat, Alkalimetallbicarbonate, z. B. Natriumbicarbonat, Kaliumbicarbonat, und Erdalkalimetallcarbonate, z. B. Calciumcarbonat, Bäriumcarbonat. Die basische Substanz kann in Form eines Gemisches, ■ einer Suspension oder Lösung im genannten inerten organischen Lösungsmittel oder im Falle einer Flüssigkeit allein verwendet werden. Falls das Ausgangsamin . der allgemeinen Formel V flüssig ist, wird ein Überschuß desselben bevorzugt, da es nicht nur als Reaktionsmittel, sondern auch als Reaktionslösungsmittel und als Mittel zur Säurebindung dienen kann.Inert solvents which can be used as the reaction medium are: water, aqueous alkanols, Alkanols, benzene, toluene, xylene, phenol and nitrobenzene. As examples of basic substances can mentioned are: organic bases, such as pyridine bases, e.g. B. pyridine, picoline, butidine, collidine, and aliphatic Amines, e.g. B. dimethylamine. Diethylamine, triethylamine, and inorganic bases, e.g. alkali metal carbonates, z. B. sodium carbonate, potassium carbonate, alkali metal bicarbonates, e.g. B. Sodium bicarbonate, Potassium bicarbonate, and alkaline earth metal carbonates, e.g. B. calcium carbonate, bearium carbonate. the basic substance can be in the form of a mixture, ■ a suspension or solution in said inert organic solvents or, in the case of a liquid, alone can be used. If the starting amine . of the general formula V is liquid, an excess of the same is preferred, since it is not only used as a reactant, but can also serve as a reaction solvent and as an acid binding agent.
Die so erhaltenen Isoxazolverbindungen der allgemeinen Formel I und II sind im freien Zustand flüssig oder fest. Zweckmäßigkeitshalber können sie bei der Herstellung in ihre Salze mit. Hilfe üblicher Verfahren umgewandelt werden. - .The isoxazole compounds of the general formulas I and II obtained in this way are in the free state liquid or solid. For convenience, they can be added to their salts during manufacture. Help usual Procedure to be converted. -.
Die so erhaltenen disubstituierten Isoxazolverbindungen der allgemeinen Formeini und II und ihre nicht toxischen Salze weisen im allgemeinen stärkere antipyretische, analgetische, entzündungshemmende und/oder hustenreizmildernde Wirksamkeiten auf als jene des Oxolamins, eines im Handel erhältlichen Medikamentes (vgl. Tabelle I).The disubstituted isoxazole compounds of the general formeini and II obtained in this way and their Non-toxic salts generally have more potent antipyretic, analgesic, anti-inflammatory and / or antitussive activities than that of oxolamine, one of the commercially available ones Drug (see Table I).

Nach Kühlung, wird das Reaktionsgemisch mit verdünnter Chlorwasserstoffsäurc geschüttelt und die wäßrige Phase mit Benzol gewaschen, mit 2%iger Natriumhydroxydlösung alkalisiert und dann mit Äther geschüttelt. Die Ätherschicht wird mit Wasser gewaschen, über wasserfreiem 'Kaliumcarbonat getrocknet und das Lösungsmittel entfernt..TDie erhaltene Flüssigkeit wird unter reduziertem ;Druck destilliert und liefert 2,1 g 3 - Dimethylaminomethyl - 5 - phenylisoxazol, in Form von hellgelblichem öl, Kp. = 132'C bei 2 mm Hg. Das Hydrochlorid besteht aus farblosen Plättchen mit F. = 223 bis 225 C, nach Kristallisie-A. To a solution of 2.9 e-3 Ohlormethyl-5-phenylisoxazole, mp = 49-50 0 C, in 20 ml of toluene, 1.5 g of dimethylamine are added and the resulting solution is then at ΓΙΟ C 8 Heated for hours. After cooling, the reaction mixture is shaken with dilute hydrochloric acid and the aqueous phase is washed with benzene, made alkaline with 2% sodium hydroxide solution and then shaken with ether. The ether layer is washed with water, dried over anhydrous potassium carbonate and the solvent is removed. The liquid obtained is distilled under reduced pressure and yields 2.1 g of 3 - dimethylaminomethyl - 5 - phenylisoxazole, in the form of a pale yellowish oil, b.p. 132'C at 2 mm Hg. The hydrochloride consists of colorless platelets with a F. = 223 to 225 C, after crystallization
