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  
EMI0001.0004     
    eine Verbindung der Formel  
EMI0001.0005     
    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     aueh    dessen  Salze, wie beispielsweise das Hydrochlorid  oder das Sulfat.  



  Als Verbindungen der Formel.     II    kommen  beispielsweise in Frage:     Piperidinoessigsäure     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-          phenoxy)-äthyl-1]-N-methylamin    oder auch  ein Salz desselben in Gegenwart eines für  diese Zwecke geeigneten wasserabspaltenden  Mittels wie     Phosphorpentoxyd,    Phosphoroxy-         chlorid        usf.    mit     Piperidinoessigsäure    behan  deln.  



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



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



  Das auf diese Weise erhaltene     N-[2-(2'-Me-          thyl-phenoxy)-äthyl-1]        -N-methyl-piperidino-          acetamid    bildet ein farbloses, unter 0,25 mm  bei 183-185  siedendes Öl.  



  Das neue     Amid    soll als Lokalanästhetikum  und als     Zwdsehenprodukt    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 20 g     Piperidinoessigsäurechlorid-          bydroehlorid    und 20 g     Triäthylamin        erwärmt.     Anschliessend wird das gebildete     Triäthyl-          aminhydrochlorid    durch Ausschütteln mit  Wasser entfernt, die     Benzollöswsg    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-mehtyl-piperidinoacetamid,    welches  ein unter 0,25 mm bei 183-185  siedendes  farbloses Öl darstellt.      Die Reaktion kann auch ohne     Verdün-          r_ungs-    und Kondensationsmittel durchge  führt werden, indem man beispielsweise das  N-     [2-(2'--'L#Ieth-%-1-phenoxy)-        äthyl-1    ]     -N-methyl-          amin    mit     Piperidinoessigsäureehlorid-hydro-          ehlorid    trocken erhitzt,

   anschliessend die Re  aktionsmasse mit Wasser verdünnt und in  üblicher 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, which is characterized in that one is based on a compound of the formula
EMI0001.0004
    a compound of the formula
EMI0001.0005
    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 conversion are: The free amine (Y = H), but also its salts, such as, for example, the hydrochloride or the sulfate.



  As compounds of the formula. II are for example: Piperidinoacetic 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- (2'-methylphenoxy) ethyl-1] -N-methylamine or a salt thereof can be treated with piperidinoacetic acid in the presence of a dehydrating agent suitable for this purpose, such as phosphorus pentoxide, phosphorus oxychloride, etc. deln.



  You can also use N- [2- (2'-methylphenoxy) ethyl-1] -N-methylamine or a. Bring the salt of the same with a piperidinoacetic acid halide (or a salt of such) or an anhydride to react.



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



  The N- [2- (2'-methyl-phenoxy) -ethyl-1] -N-methyl-piperidino-acetamide obtained in this way forms a colorless oil boiling below 0.25 mm at 183-185.



  The new amide is said to be used as a local anesthetic and as an intermediate product for the manufacture 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 20 g of piperidinoacetic acid chloride 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-piperidinoacetamide, which is a colorless oil boiling below 0.25 mm at 183-185, is thus obtained in good yield. The reaction can also be carried out without diluents and condensation agents by, for example, the N- [2- (2 '-' L # Ieth -% - 1-phenoxy) - ethyl-1] -N-methyl- amine heated dry with piperidinoacetic acid chloride hydrochloride,

   then the Re action mass diluted with water and worked up in the usual way.
