Description

  

  Verfahren zur Herstellung eines neuen basisch substituierten     Fettsäureamides.            Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    eines neuen  basisch substituierten     Fettsäureamides,    wel  ehes dadurch gekennzeichnet ist, dass man auf  eine Verbindung der Formel  
EMI0001.0005     
    eine Verbindung der Formel  
EMI0001.0006     
    in welchen Formeln X und Y reaktionsfähige,  bei der Reaktion sich abspaltende Reste be  deuten, einwirken lässt.  



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



  Als Verbindungen der Formel     II    kommen.  beispielsweise in Frage:     ss-Pyrrolidino-pro-          pionsäure    selbst und ihre reaktionsfähigen  funktionellen Derivate     wie    ihre     Halogenide,     ihre Ester, ihre     Anh@#dride,    beispielsweise die  reinen     und    auch die gemischten     Anhydride     mit Phosphorsäure, Schwefelsäure und Koh  lensäure     usf.     



  Man kann beispielsweise     N-(2-Phenoxy-          ätllyl-1)-N-methyiamin    oder auch ein Salz des  selben in Gegenwart eines für diese Zwecke  geeigneten wasserabspaltenden Mittels wie         Phosphorpentoxyd,        Phosphoroxychlorid        us-r     mit     P-Pyrrolidino-propionsäure    behandeln.  



  Weiter kann man auch     N-(2-Phenoxy-          äthyl-1)-N-methylamin    bzw. ein Salz desselben  mit einem     ss-Pyrrolidino-propionsäurehaloge-          nid    (bzw. einem Salz eines solchen) oder  einem     Anhydrid    zur     Reaktion    bringen.  



  Es ist weiterhin auch möglich,     N-(2:Phen-          oxy-äthyl-1)-N-methylamin    mit einem     ss-Pyrro-          lidino-propionsäureester,    vorzugsweise einem       Arylester,    bei erhöhter Temperatur zu     acy-          lieren.     



  Das auf diese Weise erhaltene     N-(2-Phen-          oxy-äthyl-1)    -     N-methyl    -     ss-pyrrolidino-propion-          amid    bildet ein farbloses, unter 0,06 mm bei  160-161  siedendes Öl.  



  Das neue     Amid    soll als Lokalanästhetikum  und als     Zwischenprodukt    zur Herstellung wei  terer Derivate Verwendung finden.  



  <I>Beispiel:</I>  15,2 g     N-(2-Phenoxy-äthyl-1)-N-methyl-          amin    in Benzol werden mit einer Mischung  von 20 g     ss-Pyrrolidino-propionsäurechlorid-          hydrochlorid    und 20 g     Triäthylamin    erwärmt.  Anschliessend wird das gebildete     Triäthyl-          aminhydroehlorid    durch Ausschütteln mit  Wasser entfernt, die     Benzollösung    nach dem  Trocknen verdampft und der Rückstand im  Hochvakuum destilliert.

   Man erhält so in  guter Ausbeute das     N-(2-Phenoxy-äthyl-1)-N-          methyl-ss-pyrrolidino-propionamid,    welches ein  unter 0,06 mm bei 160-l61  siedendes farb  loses Öl darstellt.      Die Reaktion kann auch ohne     Verdün-          nungs-    und Kondensationsmittel durchgeführt  werden, indem man beispielsweise das     N-(2-          l'henoxy-äthyl-1)-N-methylamin    mit     ss-Pyrro-          lidino-propionsäure-chlorid-hydrochlorid        t.rok-          ken    erhitzt.,

   anschliessend die Reaktionsmasse  mit Wasser     verdünnt-und    in     üblIeher    Weise  aufarbeitet.



  Process for the production of a new basic substituted fatty acid amide. The subject matter of the present patent is a process for the preparation of a new basic substituted fatty acid amide, which is characterized in that a compound of the formula
EMI0001.0005
    a compound of the formula
EMI0001.0006
    in which formulas X and Y are reactive residues that are split off during the reaction.



  Examples of possible compounds of the formula I for a conversion are: The free amine (Y = H), but also its salts, such as the hydrochloride or the sulfate.



  As compounds of formula II come. for example in question: ß-pyrrolidino-propionic acid itself and its reactive functional derivatives such as its halides, its esters, its anhydrides, for example the pure and also the mixed anhydrides with phosphoric acid, sulfuric acid and carbon acid etc.



  For example, N- (2-phenoxy-ätllyl-1) -N-methyiamine or a salt of the same can be treated with p-pyrrolidino-propionic acid in the presence of a dehydrating agent suitable for this purpose, such as phosphorus pentoxide, phosphorus oxychloride, etc.



  Furthermore, N- (2-phenoxyethyl-1) -N-methylamine or a salt thereof can also be reacted with an β-pyrrolidino-propionic acid halide (or a salt of such a) or an anhydride.



  It is furthermore also possible to acylate N- (2: phenoxy-ethyl-1) -N-methylamine with an β-pyrrolidino-propionic acid ester, preferably an aryl ester, at elevated temperature.



  The N- (2-phenoxy-ethyl-1) -N-methyl-ss-pyrrolidino-propionamide obtained in this way forms a colorless oil which boils below 0.06 mm at 160-161.



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



  <I> Example: </I> 15.2 g of N- (2-phenoxy-ethyl-1) -N-methyl-amine in benzene are mixed with a mixture of 20 g of ss-pyrrolidino-propionic acid chloride hydrochloride and 20 g of triethylamine warmed up. 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-phenoxy-ethyl-1) -N-methyl-ß-pyrrolidino-propionamide, which is a colorless oil boiling below 0.06 mm at 160-161, is obtained in good yield. The reaction can also be carried out without a diluent and condensation agent, for example by treating the N- (2-l'henoxy-ethyl-1) -N-methylamine with s-pyrrolidino-propionic acid chloride hydrochloride t.rok - ken heated.,

   then the reaction mass is diluted with water and worked up in the usual way.
