Description

  

  Verfahren     zur    Herstellung eines neuen basisch     substituierten        Fettsäureamides.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines neuen  basisch substituierten     Fettsäureamides,    wel  ches 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     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:     PyiTolidinoessigsäure     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-(2'-Methyl-          phexioxy)-äthyl-1]-N-methylamin    oder auch  ein Salz desselben in Gegenwart eines für  diese     Zwecke    geeigneten wasserabspaltenden       31ittels    wie     Phosphorpentoxyd,        Phosphoroxy-          ehlorid        usf,    mit     Pyrrolidinoessigsäure    behan  deln.

      Weiter kann man auch     N-[2-(2'-Methyl-          phenoxy)-äthyl-1]-N-methylamin    bzw. ein Salz  desselben mit einem     Pyrrolidinoessigsäurechlo-          rid    (bzw. einem     Salz    eines solchen) oder einem       Anhydrid    zur Reaktion bringen.  



  Es ist weiterhin auch möglich,     N-[2-(2'-          lllethyl-phenoxy)-äthyl-1]-N-methylamin    mit  einem     Pyrrolidinoessigsäureester,    vorzugsweise  einem     Arylester,    bei erhöhter Temperatur zu       acylieren.     



  Das auf diese Weise erhaltene     N-[2-(2'-Me-          thyl-phenoxy)    -     äthyl-1    ] -     N-methyl-pyrrolidino-          acetamid    bildet ein farbloses, unter 0,16 mm  bei 173-175  siedendes Öl.  



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



  <I>Beispiel:</I>  16g     N-[2-(2'-Methyl-phenoxy)-äthyl-1]-N-          methylamin    in     Benzol    werden mit einer Mi  schung von     19g        Pyrrolidinoessigsäurechlorid-          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     N-[2-(2'-Methyl-phenoxy-          äthyl-1]-N-methyl-pyrrolidinoacetamid,    wel  ches ein     unter    0,16 mm bei 173-175  sieden  des farbloses Ö1 darstellt.  



  Die Reaktion     kann    auch ohne     Verdün-          nungs-    und Kondensationsmittel durchgeführt      werden, indem man beispielsweise das N-[2  (2'-Methyl-phenoxy) -     äthyl-1    ] -N-     methylamin     mit     Pyrrolidinoessigsäure-chlorid-hydroclilo-          rid    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 of the present patent is a process for the preparation of a new basic substituted fatty acid amide, wel Ches is characterized in that one is based on 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.



  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.



  Examples of possible compounds of the formula II are: PyiTolidinoacetic 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 carbonic acid, etc.



  For example, N- [2- (2'-methylphexioxy) ethyl-1] -N-methylamine or a salt thereof can be treated with pyrrolidinoacetic acid in the presence of a dehydrating agent suitable for this purpose, such as phosphorus pentoxide, phosphorus oxychloride, etc. deln.

      Furthermore, N- [2- (2'-methylphenoxy) ethyl-1] -N-methylamine or a salt thereof can also be reacted with a pyrrolidinoacetic acid chloride (or a salt of such) or an anhydride .



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



  The N- [2- (2'-methyl-phenoxy) -ethyl-1] -N-methyl-pyrrolidino-acetamide obtained in this way forms a colorless oil boiling below 0.16 mm at 173-175.



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



  <I> Example: </I> 16 g of N- [2- (2'-methyl-phenoxy) -ethyl-1] -N-methylamine in benzene are heated with a mixture of 19 g of pyrrolidinoacetic 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- (2'-methyl-phenoxy-ethyl-1] -N-methyl-pyrrolidinoacetamide, which is less than 0.16 mm at 173-175 boiling point of the colorless oil, is thus obtained in good yield.



  The reaction can also be carried out without a diluent or condensing agent, for example by heating the N- [2 (2'-methylphenoxy) ethyl-1] -N-methylamine dry with pyrrolidinoacetic acid chloride hydrochloride. , then diluted the reac tion mass with water and worked up in the usual way.
