  Verfahren zur Herstellung eines neuen basisch substituierten Fettsäureamides.



   Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen basisch substituierten   Fettsäureamides,    welches dadurch gekennzeichnet ist,   dal3 man    auf eine Verbindung der Formel
EMI1.1     
 eine Verbindung der Formel
EMI1.2     
 in welchen Formeln X und Y reaktionsfähige, bei der Reaktion sich abspaltende Reste bedeuten, einwirken   last.   



   Als Verbindungen der Formel I kommen   fur    einen Umsatz beispielsweise in Frage : Das freie Amin (Y = H), aber auch dessen   Salé, vie    beispielsweise das Hydrochlorid oder das Sulfat.



   Als Verbindungen der Formel   II kommen    beispielsweise in Frage :   Diäthylaminessig-    saure selbst   lmd    ihre reaktionsfähigen funktionellen Derivate wie ihre Halogenide, ihre Ester, ihre Anhydride, beispielsweise die reinen und   ranch    die gemischten Anhydride mit   Phosphorsäure, Sehwefelsäure    und Kohlen  saure    usf.



   Man kann beispielsweise   N-[2-(4'-Methyl-      phenoxy)-äthyl-1]-N-methylamin    oder aucli ein Salz desselben in   Gegenwait    eines   fur      diese Zweeke    geeigneten   wasserabspáltenden    Mittels wie Phosphorpentoxyd, Phosphoroxychlorid   usf.    mit   Diäthylaminoessigsäure    behandeln.



   Weiter kann man   auch N- [2- (4'-il2ethyl-      phenoxy)-äthyl-1]-N-methylamin    bzw. ein Salz desselben mit einem Diäthylaminoessigsäurehalogenid (bzw. einem Salz eines Solchen) oder einem Anhydrid zur Reaktion bringen.



   Es ist weiterhin auch   möglieh, N-[2-(4'-    Methyl-phenoxy)-äthyl-1]-N-methylamin mit einem   Diäthylaminoessigsäureester,    vorzugsweise einem Arylester, bei erhöhter Tempera  tur    zu acylieren.



   Das auf   diese    Weise erhaltene N- [2- (4'methyl-phenyl)-äthyl-1]-N-methyl-diäthylamino-essigsäureAmid bildet ein farbloss, unter 0, 04 mm bei   139-140     siedendes   01.   



   Das neue Amid soll als   Lokalanästhetikom    und als   Zwisehenprodukt    zur Herstellung weiterer Derivate Verwendung finden.



   Beispiel :
16 g N- [2-   (4'-Methyl-phenoxy)-athyl-1]-I-    methylamin in Benzol werden mit einer   Mi-    schung von 18 g   Diathylaminoessigsaure-ehlo-    rid-hydrochlorid und 20 g Triäthylamin erwärmt. Anschliessend wird das gebildete Tri ätjhylaminhdyrochlorid durch Ausschütteln init Wasser entfernt, die   Benzollösung naeh    dem Trocknen verdampft und der   Rückstand    im   Hoehvakuum    destilliert. Man erhält so in   ,, uter    Ausbeute das N- [2- (4'-Methyl-phenoxy)   äthyl-1]-N-methyl-diäthylamino-essigsäure-    amid, welches ein unter 0, 04 mm bei   139140     siedendes farbloses   öl    darstellt.



   Die Reaktion kann auch ohne Verdiinnungs- und Kondensationsmittel duirchgeführt werden, indem man beispielsweise das   N- [2-       (4'-Methyl-phenoxy)-äthyl-1]-N-methylamin    mit   Diäthylamino-essigsäure-ehlorid-hydro-      chloxid trocken    erhitzt,   ansehliessend    die Reaktionsmasse mit Wasser verdünnt und in üblicher Weise aufarbeitet.



  



  Process for the production of a new basic substituted fatty acid amide.



   The present patent relates to a process for the preparation of a new basic substituted fatty acid amide, which is characterized in that a compound of the formula
EMI1.1
 a compound of the formula
EMI1.2
 in which formulas X and Y mean reactive residues which are split off during the reaction last.



   Compounds of the formula I that can be used for conversion include, for example: the free amine (Y = H), but also its sale, such as the hydrochloride or the sulfate.



   Examples of compounds of the formula II are: diethylamine acetic acid itself and its reactive functional derivatives such as its halides, its esters, its anhydrides, for example the pure and mixed anhydrides with phosphoric acid, sulfuric acid and carboxylic acid, etc.



   For example, N- [2- (4'-methylphenoxy) ethyl-1] -N-methylamine or also a salt thereof can be treated with diethylaminoacetic acid in the presence of a water-removing agent such as phosphorus pentoxide, phosphorus oxychloride, etc.



   N- [2- (4'-il2ethylphenoxy) ethyl-1] -N-methylamine or a salt thereof can also be reacted with a diethylaminoacetic acid halide (or a salt of one of these) or an anhydride.



   It is also possible to acylate N- [2- (4'-methyl-phenoxy) -ethyl-1] -N-methylamine with a diethylaminoacetic acid ester, preferably an aryl ester, at an elevated temperature.



   The N- [2- (4'methyl-phenyl) -ethyl-1] -N-methyl-diethylamino-acetic acid amide obtained in this way forms a colorless oil that boils below 0.04 mm at 139-140.



   The new amide will be used as a local anesthetic and as an intermediate product for the production of further derivatives.



   Example:
16 g of N- [2- (4'-methyl-phenoxy) -ethyl-1] -imethylamine in benzene are heated with a mixture of 18 g of diethylaminoacetic acid-chloride hydrochloride and 20 g of triethylamine. The triethylamine hydrochloride formed is then removed by shaking with water, the benzene solution is evaporated after drying and the residue is distilled in a high vacuum. The N- [2- (4'-methyl-phenoxy) ethyl-1] -N-methyl-diethylamino-acetic acid amide, which is a colorless oil boiling below 0.04 mm at 139140, is thus obtained in good yield .



   The reaction can also be carried out without diluting and condensing agents by, for example, heating the N- [2- (4'-methyl-phenoxy) -ethyl-1] -N-methylamine with diethylaminoacetic acid chloride hydrochloride dry , then diluted the reaction mass with water and worked up in the usual way.
