  Verfahren zur Herstellung eines neuen basisch     substituierten        Fettsäureamides.       Gegenstand des vorliegenden Patentes ist       rin    Verfahren zur Herstellung eines neuen       basiseh    substituierten     Fettsäureamides,        wel-          elies    dadurch gekennzeichnet ist, dass man auf  eine     Verbindung    der Formel  
EMI0001.0009     
    eine     Verbindung    der Formel  
EMI0001.0011     
    in welchen     Formeln    X und Y reaktionsfähige,  bei der Reaktion sich abspaltende Reste be  deuten, einwirken lässt.  



  Als Verbindungen der Formel I kommen  für     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:     a-Pyrrolidinopropion-          säure    selbst und ihre reaktionsfähigen funk  tionellen Derivate wie ihre     Halogenide,    ihre  Ester, ihre     Anhydride,    beispielsweise die rei  nen und auch die gemischten     Anhydride    mit  Phosphorsäure,     Sehwefelsäure    und     Kohlen-          Säure        usf.     



  Man kann beispielsweise     N-(2-Phenoxy-          äthyl-7        )-N-methylamin    oder auch ein Salz des  selben in Gegenwart eines für diese Zwecke       geeigneten    wasserabspaltenden     Mittels    wie         Phosphorpentoxyd,        Phosphoroxychlorid        usf.     mit     a-Pyrrolidinopropionsäure    behandeln.  



  Weiter kann man auch     N-(2-Phenoxy-          äthyl-1)-N-methylamin    bzw. ein Salz desselben  mit einem     a-Pyrrolidino-propionsäure-haloge-          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     a-Pyrro-          lidino-propionsäureester,    vorzugsweise einem       Arylester,    bei erhöhter Temperatur zu     acy-          lier    en.  



  Das auf diese Weise erhaltene     N-(2-Phen-          oxy-äthyl-1)    - N -     meth@,l-a-pyrr        olidino-propion-          amid    bildet ein farbloses, unter 0,06 mm bei       l40-141     siedendes Öl.  



  Das neue     Amid    soll     als        Lokalanästhetikum     und als     Zwisehenprodukt    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     a-Pyrrolidino-propionsäurechlorid-          hydroehlorid    und 20,2 g     Triäthylamin    er  wärmt.

   Anschliessend wird das gebildete     Tri-          äthyla.minhydrochlorid    durch Ausschütteln  mit Wasser entfernt, die     Benzollösung    nach  dem Trocknen verdampft und der Rückstand  im     I-Iochvakuum    destilliert. Man erhält so in  guter Ausbeute das     N-(2-Phenoxy-äthyl-1.)-N-,        methyl-a-pyrrolidino-propionamid,    welches ein  unter 0,06 mm bei 140--141  siedendes farb  loses Öl darstellt.

        Die Reaktion kann auch ohne     Verdün-          nungs-    und Kondensationsmittel durchgeführt  werden, indem man beispielsweise das     a-Pyrro-          lidino-propionsäurechlorid-hydrochlorid    mit       N-(2-Phenoxy-äthyl-1)-N-methylamin    trocken  erhitzt, anschliessend die Reaktionsmasse mit  Wasser verdünnt und in üblicher     Weise    auf  arbeitet.



  Process for the production of a new basic substituted fatty acid amide. The subject matter of the present patent is a process for the production of a new basic substituted fatty acid amide, which is characterized in that one accesses a compound of the formula
EMI0001.0009
    a compound of the formula
EMI0001.0011
    in which formulas X and Y are reactive residues that are split off during the reaction.



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



  Examples of possible compounds of the formula II are: a-pyrrolidinopropionic 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 carbonic acid, etc. .



  For example, N- (2-phenoxyethyl-7) -N-methylamine or a salt of the same can be treated with α-pyrrolidinopropionic acid in the presence of a dehydrating agent suitable for this purpose, such as phosphorus pentoxide, phosphorus oxychloride, etc.



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



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



  The N- (2-phenoxy-ethyl-1) - N - meth @, l-a-pyrrolidino-propionamide obtained in this way forms a colorless oil boiling below 0.06 mm at 140-141.



  The new amide is to be used as a local anesthetic and as an intermediate product for the production of further derivatives. <I> Example: </I> 15.2 g of N- (2-phenoxy-ethyl-1) -N-methyl-amine in benzene are hydrochloride with a mixture of 20 g of a-pyrrolidino-propionic acid chloride and 20.2 g triethylamine he warms.

   The triethyla.min hydrochloride formed is then removed by shaking with water, the benzene solution is evaporated after drying and the residue is distilled in a vacuum. The N- (2-phenoxy-ethyl-1.) - N-, methyl-a-pyrrolidino-propionamide, which is a colorless oil boiling below 0.06 mm at 140--141, is obtained in good yield.

        The reaction can also be carried out without diluents and condensation agents, for example by heating the α-pyrrolidino-propionic acid chloride hydrochloride with N- (2-phenoxy-ethyl-1) -N-methylamine dry, then heating the reaction mass with it Dilute water and work on in the usual way.
