Description

  

  Verfahren zur Darstellung eines     acylierten,        aliphatischen        Aminocarbonsäureamii#\s7       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines       acylierten,        aliphatischen        Aminocarbonsäure-          amids.    Das Verfahren ist dadurch gekenn  zeichnet, dass     N-Acetyl-a-(n-propylamino)-n-          buttersäureamid    am     Amidstickstoff    bis zum  Ersatz beider Wasserstoffatome     methyliert     wird.  



  Das     N-Acetyl-a-(n-propylamino)-n-butter-          säuredimethylamid    der Formel  
EMI0001.0014     
    bildet eine farblose Flüssigkeit vom Siede  punkt 129  unter 0,31 mm.  



  Die neue Verbindung soll therapeutische  Verwendung finden.         Beispiel:          26-    Teile     a-(n-Propylamino)-n-buttersäure-          amid    werden in Chloroform gelöst und bei  t)  mit 7,8 Teilen     Acetylchlorid    zur Reak  tion gebracht. Vom     a-(n-Propylamino)-n-but-          tersäureamid-chlorhydrat    wird filtriert und  das Chloroform     abdestilliert.    Der Rückstand  wird in 200 Teilen     Xylol    aufgenommen und  mit 10 Teilen     Natriumamid    eine. Stunde zum  Sieden erhitzt.

   Nach dem Abkühlen werden  38 Teile     Kalium-methylsulfat    zugegeben und    anschliessend     wird    im Druckgefäss auf 180 bis  190  erhitzt. Nach beendeter Reaktion wie  derholt man die Behandlung mit     Natrium-          amid    und     Kalium-methylsulfat.    Dann giesst  man auf Eis, sättigt die     wä.ssrige    Lösung mit  festem     Kaliumhydrogyd    und trennt die       Xylollösung    ab. Das Lösungsmittel wird ab  destilliert und der Rückstand im Hochvakuum  rektifiziert. Die neue Verbindung zeigt den  Siedepunkt 129  unter 0,31 mm und ist leicht  löslich in Wasser und organischen Lösungs  mitteln. .



  Process for the preparation of an acylated, aliphatic aminocarboxylic acid amide The subject of the present additional patent is a process for the preparation of an acylated, aliphatic aminocarboxamide. The process is characterized in that N-acetyl-a- (n-propylamino) -n-butyric acid amide is methylated on the amide nitrogen until both hydrogen atoms are replaced.



  The N-acetyl-a- (n-propylamino) -n-butyric acid dimethylamide of the formula
EMI0001.0014
    forms a colorless liquid with a boiling point of 129 below 0.31 mm.



  The new compound should find therapeutic use. Example: 26 parts of a- (n-propylamino) -n-butyric acid amide are dissolved in chloroform and reacted with 7.8 parts of acetyl chloride at t). The a- (n-propylamino) -n-but-acid amide chlorohydrate is filtered off and the chloroform is distilled off. The residue is taken up in 200 parts of xylene and treated with 10 parts of sodium amide. Heated to the boil for an hour.

   After cooling, 38 parts of potassium methyl sulfate are added and the mixture is then heated to 180 to 190 in a pressure vessel. After the reaction has ended, the treatment with sodium amide and potassium methyl sulfate is repeated. Then it is poured onto ice, the aqueous solution is saturated with solid potassium hydrogen and the xylene solution is separated off. The solvent is distilled off and the residue is rectified in a high vacuum. The new compound has a boiling point of 129 below 0.31 mm and is easily soluble in water and organic solvents. .
