Description
Verfahren zur Darstellung eines basischen Esters. Es wurde gefunden, dass man zu dem im Patent Nr.<B>215775</B> beschriebenen Phenyl- cyclohexyl - essigsäure - @diäthylaminoäthanol- ester auch gelangen kann, wenn man auf einer Verbindung der Formel
EMI0001.0006
worin X einen bei der Reaktion sich abspal tenden Rest bedeutet, wie z. B. Phenyl-cyclo- hexyl-essigsäure, ihre Halogenide, Ester oder ihr Anhydrid, Diäthylaminoäthanol -einwir ken lässt.
Die so erhaltene Verbindung soll thera peutische Verwendung finden.
Beispiel <I>1:</I> 22 Teile Phenyl - cyclohexyl - essigsäure werden mit Hilfe von Thionylchlorid in üblicher Weise in das. Säurechlorid überge führt und dieses mit 12 Teilen Diäthylamino- äthanol umgesetzt. Nach beendigter Reaktion fügt man Wasser, galiumkarbonatlösung und Äther zu und schüttelt kräftig .durch.
Die ätherische Lösung wird mit Wasser ge waschen, über galiumkarbonat getrocknet und eingedampft. Man erhält so Phenyl- cyclohexyl - essigsäure - diäthylaminoäthanol- ester vom gpo",; 158 .
An Stelle des Säurechlorids kann auch z. B. das Säurebromid hergestellt und zur Umsetzung verwendet werden.
Dieselbe Verbindung kann auch gewon nen werden, wenn man einen Phenyl-cyclo- hexyl - essigsäureester mit Diäthylamino- äthanol in der Wärme umsetzt und das Re aktionsprodukt im Vakuum fraktioniert @de- stilliert.
Die Umsetzung kann zweckmässig auch in Gegenwart eines Lösungsmittels, wie z. B. Benzol, Toluol, Äther, Chlorbenzol und,der- gleichen, vorgenommen werden. <I>Beispiel 2:</I> 22 Teile Phenyl - cyolohexyl - essigsäure werden mit 12 Teilen Diäthylaminoäthano:l innig vermischt. Hierauf fügt man s Teile Phosphoroxychlorid hinzu und erwärmt das Gemisch bis zur beendigten Umsetzung.
Man arbeitet in der in Beispiel 1 beschriebenen Weise auf und erhält so denselben Endstoff.
An Stelle von Phosphoroxyehlorid können auch andere geeignete Kondensationsmittel, wie z. ss. Phosphorpentoxyd, Phosphortri- chlorid, Phosphorpentachlorid, Phosgen, Py- ridin, Thionylchlorid oder Säuren, wie z. ss. Salzsäure, Verwendung finden.
Process for the preparation of a basic ester. It has been found that the phenyl-cyclohexyl-acetic acid-diethylaminoethanol ester described in patent no. 215775 can also be obtained by using a compound of the formula
EMI0001.0006
wherein X is a residue that splits off in the reaction, such as. B. phenyl-cyclohexyl-acetic acid, its halides, esters or anhydride, diethylaminoethanol -einwir ken.
The compound obtained in this way is intended to be used therapeutically.
Example <I> 1 </I> 22 parts of phenyl-cyclohexyl-acetic acid are converted into the acid chloride in the customary manner with the aid of thionyl chloride, and this is reacted with 12 parts of diethylaminoethanol. When the reaction is complete, add water, galium carbonate solution and ether and shake vigorously.
The ethereal solution is washed with water, dried over galium carbonate and evaporated. Phenylcyclohexyl acetic acid diethylaminoethanol ester from gpo ",; 158 is thus obtained.
Instead of the acid chloride, z. B. the acid bromide produced and used for the implementation.
The same compound can also be obtained if a phenylcyclohexyl acetic acid ester is reacted with diethylaminoethanol in the heat and the reaction product is fractionated @ distilled in vacuo.
The reaction can conveniently also in the presence of a solvent, such as. B. benzene, toluene, ether, chlorobenzene and the like can be made. <I> Example 2 </I> 22 parts of phenyl-cyolohexyl-acetic acid are intimately mixed with 12 parts of diethylaminoethano: l. Parts of phosphorus oxychloride are then added and the mixture is heated until the reaction has ended.
Working up in the manner described in Example 1 gives the same end product.
Instead of phosphorus oxychloride, other suitable condensing agents, such as. ss. Phosphorus pentoxide, phosphorus trichloride, phosphorus pentachloride, phosgene, pyridine, thionyl chloride or acids, such as. ss. Hydrochloric acid, use.
