Description

  

  Verfahren zur Herstellung eines neuen basisch substituierten     Fettsäureamides.       Gegenstand des vorliegenden Patentes bil  det ein Verfahren zur Herstellung eines neuen  basisch     substituierten        Fettsäurea.mides,        wel.-          ehes    dadurch     gekennzeichnet.    ist, dass man eine  Verbindung der Formel,  
EMI0001.0007     
    in     welcher    X einen reaktionsfähigen, während  der Reaktion sich abspaltenden Rest bedeutet,  mit     Pyrrolidin    umsetzt.  



  Der Rest X kann in einem Halogenatom  oder einem sonstigen für den Austausch gegen  den basischen Rest. geeigneten reaktionsfähi  gen     Substituenten,        wie    z. B. einer     Alkylsul-          fonyioxy-    oder     Arylsulfonyloxygruppe,    beste  lien. Der     Austausch    der Gruppe X gegen den       Pyrrolidinorest    erfolgt z. B. durch einfaches       Erwärmen    mit.     Pyrrolidin,    gegebenenfalls in  Gegenwart. eines basisch reagierenden     Kon-          densationsmittels    oder von     Pvrrolidin    im  Überschuss.

   Das     Pyrrolidinoessigsäure-N-    (3  phenoxy-propyl-2)-amid ist. ein farbloses, un  ter 0,07 mm bei 143-144  siedendes Öl.  



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



       Beispiel:     45,0g Chlor     essigsäur        e-2NT-        (3-phenoxy-pro-          py1--.)-amid    und 30,0 g     Pyrrolidin    werden zu-         sammen    in 300     cms        abs.    Benzol 4 Stunden auf  dem Wasserbad erhitzt.. Das Reaktionsgemisch  wird mit     Wasser        ausgeschüttelt    und dann mit       2n-Salzsäure    ausgezogen.

   Darauf wird der  salzsaure     Auszug    mit Äther extrahiert, unter  Eiskühlung mit     konz.    Natronlauge versetzt       lind    das     ausgeschiedene    Öl in Äther aufge  nommen. Nach dem Trocknen der Ätheraus  züge über Pottasche wird der Äther verdampft  und der Rückstand im Hochvakuum     destilliert.     



  Dabei gewinnt. man das unter 0,07 mm bei  143-144  siedende     Pyrrolidinoessigsäure-N-          (3-phenoxy-propyl-2)-a.mid    in einer Ausbeute  von 78     1/o-    der Theorie. Farbloses Öl, schwer  löslich in Wasser, gut in     organischen    Lösungs  mitteln und     in.    verdünnten Mineralsäuren.



  Process for the production of a new basic substituted fatty acid amide. The subject of the present patent bil det a process for the production of a new basic substituted Fettsäurea.mides, wel.- ehes characterized. is that you can find a compound of the formula
EMI0001.0007
    in which X is a reactive radical which is split off during the reaction, reacts with pyrrolidine.



  The radical X can be in a halogen atom or another for the exchange against the basic radical. Suitable reactive substituents such. B. an alkylsulfonyioxy or arylsulfonyloxy group, best lien. The exchange of group X against the pyrrolidino radical takes place, for. B. by simply heating with. Pyrrolidine, optionally in the presence. a basic condensing agent or an excess of pvrrolidine.

   The pyrrolidinoacetic acid N- (3-phenoxy-propyl-2) -amide is. a colorless oil boiling below 0.07 mm at 143-144.



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



       Example: 45.0 g of chloroacetic acid e-2NT- (3-phenoxy-propy1 -.) - amide and 30.0 g of pyrrolidine are added together in 300 cms abs. Benzene heated on a water bath for 4 hours. The reaction mixture is extracted by shaking with water and then extracted with 2N hydrochloric acid.

   The hydrochloric acid extract is then extracted with ether, with conc. Sodium hydroxide is added and the excreted oil is absorbed in ether. After the ether extracts have dried over potash, the ether is evaporated and the residue is distilled in a high vacuum.



  It wins. the pyrrolidinoacetic acid-N- (3-phenoxy-propyl-2) -a.mid boiling below 0.07 mm at 143-144 in a yield of 78 1 / o of theory. Colorless oil, sparingly soluble in water, good in organic solvents and in dilute mineral acids.
