Description

  

  Verfahren     zur        Herstellung    eines neuen basisch     substituierten        Fettsäureamides.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines neuen  basisch substituierten     Pettsäureamides,    wel  ches dadurch gekennzeichnet ist,     da.ss    man auf  eine Verbindung der Formel  
EMI0001.0007     
    eine Verbindung der Formel  
EMI0001.0008     
    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:     Pvrrolidinoessigsäure     selbst und ihre reaktionsfähigen funktionellen  Derivate wie ihre     Halogenide,    ihre Ester, ihre       Anhydride,    beispielsweise die reinen und auch  die gemischten     Anhydride    mit Phosphorsäure,       Schwefelsäure    und Kohlensäure     usf.     



  Man kann beispielsweise     N-[2-(4'-i@Iethyl-          phenoxy        )-äthyl-1]-N-methylamin    oder auch  ein Salz desselben in Gegenwart eines für  diese Zwecke geeigneten wasserabspaltenden  Mittels wie     Phosphorpentoxyd,    Phosphoroxy-         ehlorid        usf.    mit     Pyrrolidinoessigsäure    be  handeln.  



  Weiter kann man auch     N-[2-(4'-?1lethyl-          phenoxy)-äthyl-1]-N-methylamin    bzw. ein Salz  desselben mit einem     Pyrrolidinoessigsäure-          halogenid    (bzw. einem Salz eines solchen)  oder einem     Anhydrid    zur Reaktion bringen.  



  Es ist weiterhin auch möglich,     N-[2-(4'-          Methyl-phenoxy)        -äthyl-1    ] - N -     methylamin    mit  einem     Pyrrolidinoessigsäureester,    vorzugs  weise einem     Arylester,    bei erhöhter Tempera  tur zu     aeylieren.     



  Das auf diese Weise erhaltene     N-[2-(4'-Me-          thyl-phenoxy)    -     äthyl-1    ] -     N-methyl-pyrrolidino-          acetamid    bildet ein farbloses, unter 0,06 mm  bei     150-15P    siedendes Öl.  



  Das neue     Amid    soll als Lokalanästhetikum  und als Zwischenprodukt zur Herstellung  weiterer Derivate Verwendung finden,    <I>Beispiel:</I>    16g     N-[2-(4'-Methyl-phenoxy)-äthyl-1]-N-          methylamin    in Benzol werden mit     einer    Mi  schung von 19 g     Pyrrolidinoessigsäure-ehlorid-          hydrochlorid    und 20 g     Triäthylamin    erwärmt.

    Anschliessend wird das gebildete     Triäthyl-          aminhydrochlorid    durch Ausschütteln mit  Wasser entfernt, die     Benzollösung    nach dem       Trocknen        verdampft    und der Rückstand     im     Hochvakuum destilliert. Man erhält so     in     guter Ausbeute das     lNT-[2-(4'-1Iethyl-phenoxy)-          äthyl-1]-N-methyl-pyrrolidinoacetamid,    wel  ches ein     unter    0,06 mm bei 150-151  sieden  des farbloses Öl darstellt.

        Die Reaktion kann auch ohne     Verdün-          nungs-    und     Kondensationsmittel-durchgeführt     werden, indem man beispielsweise das     N-[2-          (4'-llethyl-phenoxy)    -     äthyl-1    ]     -N-methy        lamin     mit     Pyrroliclinoessigsäure-chlorid-hydroehlo-          r        id    trocken     erhitzt,    anschliessend die Reak  tionsmasse mit Wasser verdünnt und in übli  cher 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 is used
EMI0001.0007
    a compound of the formula
EMI0001.0008
    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, for example.



  Compounds of the formula II are, for example: Pvrrolidinoacetic 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- (4'-i @ methylphenoxy) -ethyl-1] -N-methylamine or a salt thereof in the presence of a dehydrating agent suitable for this purpose, such as phosphorus pentoxide, phosphorus oxychloride, etc., can be used Treat pyrrolidinoacetic acid.



  Furthermore, N- [2- (4 '-? 1lethylphenoxy) -ethyl-1] -N-methylamine or a salt thereof with a pyrrolidinoacetic acid halide (or a salt of such) or an anhydride can also be used for the reaction bring.



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



  The N- [2- (4'-methyl-phenoxy) -ethyl-1] -N-methyl-pyrrolidino-acetamide obtained in this way forms a colorless oil boiling below 0.06 mm at 150-15P.



  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> 16 g of N- [2- (4'-methyl-phenoxy) -ethyl-1] -N-methylamine in benzene are heated with a mixture of 19 g of pyrrolidinoacetic acid ehlorid 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 INT- [2- (4'-1-ethyl-phenoxy) -ethyl-1] -N-methyl-pyrrolidinoacetamide, which represents a colorless oil below 0.06 mm at 150-151 boiling point, is thus obtained in good yield.

        The reaction can also be carried out without a diluent and condensing agent, for example by adding hydrochloride of the N- [2- (4'-llethyl-phenoxy) -ethyl-1] -N-methylamine with pyrroliclinoacetic acid chloride id heated dry, then diluted the reac tion mass with water and worked up in the usual way.
