Description
Verfahren zur Herstellung eines neuen basisch substituierten Fettsäureamides. (legenstand des vorliegenden Patentes bil det ein Verfahren zur Herstellung eines neuen Insiseh substituierten Fettsäureamides, wel ches dadurch gekennzeichnet ist, dass man eine Verbindung der Formel
EMI0001.0006
in welcher X einen reaktionsfähigen, während der Reaktion sich abspaltenden Rest. bedeutet, mit. Diäthylamin umsetzt.
Der Rest X kann in einem Halogenatom oder einem sonstigen für den Austausch gegen den basischen Rest geeigneten reaktionsfähi gen Substituenten, wie zum Beispiel einer Al- liyisulfonyloxy- oder Arylsulfonyloxygruppe, bestehen. Der Austausch der Gruppe X gegen den Diäthylaminorest erfolgt zum Beispiel durch einfaehes Erwärmen mit Diäthvlamin, gegebenenfalls in Gegenwart eines basisch reagierenden Kondensationsmittels oder von Diäthylamin im Überschuss,
Das Diäthyl- aminoessigsäure-N- (3-p-methoxy -phenoxy-pro- pyl-2)-methylamid ist ein farbloses, unter 0,015 mm bei 158-159 siedendes Öl.
Das neue Amid soll als Lokalanästhetikum und als Zwischenprodukt zur Herstellung weiterer Derivate Verwendung finden.
<I>Beispiel:</I> 21,0 g Chloressigsäure-N- (3-p-metlioxy- phenoxy-propyl-2)-methylamid und 16,9 g Di- äthylamin werden zusammen in 200 ein- abs. Benzol 5 Stunden auf dem Wasserbad erhitzt. Das Reaktionsgemisch wird mit Wasser aus geschüttelt und dann mit 2n-Salzsäure aus gezogen.
Darauf wird der salzsaure Auszug mit Äther extrahiert, unter Eiskühlung mit konz. Natronlauge versetzt und das ausge schiedene Öl in Äther aufgenommen. Nach dem Trocknen der Ätherauszüge über Pott asche wird der Äther verdampft und der Rückstand im Hochv akuiun destilliert.
Dabei gewinnt man das -unter 0,015 mm bei 158-159 siedende Diäthylaminöessig- sä,ure-N- (3-p-methoxy- phenoxy-propyl-2) -me- thylamid in einer Ausbeute von 72% der Theorie, Farbloses Öl, schwer löslieh in Was ser, gut in organischen Lösungsmitteln und in verdünnten Mineralsäuren.
Process for the production of a new basic substituted fatty acid amide. (the status of the present patent forms a process for the production of a new insiseh substituted fatty acid amide, which is characterized in that a compound of the formula

in which X is a reactive radical which is split off during the reaction., with. Diethylamine converts.
The radical X can consist of a halogen atom or another reactive substituent suitable for replacement with the basic radical, such as, for example, an allyisulfonyloxy or arylsulfonyloxy group. Group X is exchanged for the diethylamino radical, for example, by simple heating with diethylamine, if necessary in the presence of a basic condensing agent or excess diethylamine,
Diethylaminoacetic acid N- (3-p-methoxy-phenoxy-propyl-2) -methylamide is a colorless oil that boils at 158-159 below 0.015 mm.
The new amide is to be used as a local anesthetic and as an intermediate for the production of other derivatives.
<I> Example: </I> 21.0 g of chloroacetic acid-N- (3-p-metlioxy- phenoxy-propyl-2) -methylamide and 16.9 g of diethylamine are mixed together in 200 one-abs. Benzene heated on a water bath for 5 hours. The reaction mixture is shaken out with water and then drawn off with 2N hydrochloric acid.
The hydrochloric acid extract is then extracted with ether, with conc. Sodium hydroxide was added and the separated oil was added to ether. After the ether extracts have dried over pot ash, the ether is evaporated and the residue is distilled in a high-voltage battery.
In this way, the diethylaminoacetic acid, boiling below 0.015 mm at 158-159, is obtained, ure-N- (3-p-methoxyphenoxypropyl-2) -methylamide in a yield of 72% of theory, colorless oil, Hardly soluble in water, good in organic solvents and in dilute mineral acids.
