Description
Verfahren zur Herstellung von Triphenylessigsäure-2-diäthylaminoäthanolestea-. Es wurde gefunden, dass man zu Tri- phenylessigsäure - 2 - diäthylaminoäthanolester gelangen kann, wenn man auf eine Verbin dung, die das Radikal der Triphenylessig- säure enthält, wie zum Beispiel ihre Ester oder Halogenide oder ihr Anhydrid, 2-Diäthy 1- aminoätharrol einwirken lässt.
Der so erhaltene Triphenylessigsäure-2- diäthylaminoäthanolester siedet bei 160 bis 170 unter 0,07 mm Druck, schmilzt bei 85 bis 90 , bildet ein Hydrochlorid vom F. 164 bis<B>167</B> , ein Jodmethylat vom F. 223 bis <B>2250</B> und ein Chlormethylat vom F. 198 bis <B>1990.</B>
Die neue Verbindung soll therapeutische Verwendung finden.
<I>Beispiel:</I> 30 Teile Triphenylessigsäurechlorid setzt man mit 24 Teilen Diäthylaminoäthanol um, nimmt die Reaktionsmasse in Äther auf, wäscht die ätherische Lösung mit verdünn ter Natriuwcarbonatlösung, trocknet sie über Kaliumcarbonat und destilliert nach dem Verdampfen des Lösungsmittels den entstan denen Triphenylessigsäure-2-diäthylamirro- äthanolester im Hochvakuum.
An Stelle von Triphenylessigsäurechlorid kann auch ein anderes Halogenid, wie zum Bei spiel Triphenylessigsäurebromid Verwendung finden. Dieselbe Verbindung wird auch ge wonnen, wenn man äquivalente Mengen Tri- phenylessigsäuremethylester und 2-Diäthyl- aminoäthanol in der Wärme umsetzt und das Reaktionsprodukt im Vakuum fraktioniert destilliert. Auch andere Triphenylessigsäure- ester können als Ausgangsmaterial dienen.
Process for the preparation of triphenylacetic acid-2-diethylaminoethanolestea-. It has been found that triphenylacetic acid - 2 - diethylaminoethanol ester can be obtained if one accesses a compound which contains the radical of triphenylacetic acid, such as, for example, its esters or halides or its anhydride, 2-diethy 1- aminoätharrol can act.
The triphenylacetic acid-2-diethylaminoethanol ester thus obtained boils at 160 to 170 under 0.07 mm pressure, melts at 85 to 90, forms a hydrochloride from F. 164 to <B> 167 </B>, an iodine methylate from F. 223 to <B> 2250 </B> and a chloromethylate from F. 198 to <B> 1990. </B>
The new compound should find therapeutic use.
<I> Example: </I> 30 parts of triphenylacetic acid chloride are reacted with 24 parts of diethylaminoethanol, the reaction mass is taken up in ether, the ethereal solution is washed with dilute sodium carbonate solution, dried over potassium carbonate and the resulting distilled after evaporation of the solvent Triphenylacetic acid-2-diethylamirro- äthanolester in a high vacuum.
Instead of triphenylacetic acid chloride, another halide, such as triphenylacetic acid bromide, can also be used. The same compound is also obtained if equivalent amounts of methyl triphenylacetate and 2-diethylaminoethanol are reacted in the heat and the reaction product is fractionally distilled in vacuo. Other triphenylacetic acid esters can also serve as starting material.
