  <B>Verfahren zur Herstellung eines</B>     Tropasäure-N-(ss-picolyl)-N-alkenylamides.       Es wurde gefunden, dass     Tropasäureamide-          der    allgemeinen Formel  
EMI0001.0004     
    in der R einen     Alkenylrest,    z. B. eine     Allyl-          gruppe,    bedeutet, gute     spasmolytische        Eigen-          sehaften    zeigen.  



  Die neuen Verbindungen werden erfin  dungsgemäss durch Kondensation eines gege  benenfalls     0-acylierten        Tropasäurehalogenids     mit einem     Alkenyl-(f-picolyl)-amin,    gegebe  nenfalls     gefolgt    von der Abspaltung der       0-Acylgruppe,    hergestellt.  



  Die     Alkenyl-(ss-picolyl)-amine    können bei  spielsweise durch Umsetzung von     3-Halogen-          methyl-pyridin    mit einem primären     Alkenyl-          amin    oder durch     Alkenylierung    von     N-(p-To-          luolsulfonyl)-3-aminomethyl-pyridin    mit einem       Alkenylhalogenid    oder     Alkenylsulfat    und nach  folgende     Enttosylierung    gewonnen werden.  



  Gegenstand des Patentes ist ein Verfah  ren zur Herstellung eines     Tropasäure-N-alke-          nyl-N-(ss-picolyl)-amides,    das dadurch gekenn  zeichnet ist, dass man ein     Acyltropasäurehalo-          genid    mit     Allyl-(ss-picolyl)-amin    umsetzt und  die     0-Acylgruppe    abspaltet.

           Beispiel:     Unter Schütteln     fügt    man eine Lösung  von 32,8     Gewichtsteilen    3-Chlormethyl-pyri-         din-chlorhydrat    in 40     Gewichtsteilen    Wasser  nach     und    nach in 70 Gewichtsteile     Allylamin,     wobei die Temperatur unterhalb 10  C gehal  ten wird. Man schüttelt noch zwei Stunden  bei Raumtemperatur, dann eine weitere Stunde  bei 40  C, kühlt mit Eis und     sättigt    mit festem       Kaliumhydroxyd.    Die obere Schicht trennt  man ab.

   Beim Destillieren der letzteren geht  zuerst     unter    gewöhnlichem Druck das nicht  umgesetzte     Allylamin    und dann bei 120  C  unter einem Drucke von 13 mm     Rg    das     Allyl-          (ss-picolyl)-amin    über.  



  Zu einer Mischung von 74 Gewichtsteilen       Allyl-(ss-picolyl)-amin        (Kp.13    120  C) und 45       Gewichtsteilen    trockenem     Pyridin    in 250 Ge  wichtsteilen trockenem Chloroform wird rohes,  aus 85 Gewichtsteilen     Tropasäure    durch     Ein-          wirkung    von     Acetylchlorid    und anschliessen  der Behandlung mit überschüssigem     Thionyl-          chlorid    erhaltenes     Acetyltropasäurechlorid    un  ter Rühren und     Eiswasserkühlung    nach und  nach zugegeben.

   Zum Schluss wird noch eine       Stunde    bei gewöhnlicher Temperatur gerührt.  



  Dann wird die     Chloroformlösung    mit 250       Gewichtsteilen    Äther verdünnt     und    mit     3n-          Salzsäure    geschüttelt. Die schwach kongosaure  Lösung wird eine Stunde lang auf dem Dampf  bad erwärmt, wobei die     Acetylgruppe    des Re  aktionsproduktes abgespalten     wird.    Man fil  triert über Kohle und versetzt mit überschüs  sigem, konzentriertem Ammoniak.

   Das ausge  fallene Kondensationsprodukt wird in Chloro  form aufgenommen, das Chloroform getrock  net und     destilliert.    Das zurückbleibende

  <B> Process for the preparation of </B> a tropic acid-N- (ss-picolyl) -N-alkenylamide. It has been found that tropic acid amide- of the general formula
EMI0001.0004
    in R is an alkenyl radical, e.g. B. an allyl group, means showing good spasmolytic properties.



  The new compounds are in accordance with the invention by condensation of an optionally 0-acylated tropic acid halide with an alkenyl- (f-picolyl) -amine, optionally followed by the cleavage of the 0-acyl group.



  The alkenyl (ss-picolyl) amines can, for example, by reacting 3-halomethyl-pyridine with a primary alkenyl amine or by alkenylating N- (p-toluenesulfonyl) -3-aminomethyl-pyridine with a Alkenyl halide or alkenyl sulfate and can be obtained after subsequent detosylation.



  The subject of the patent is a process for the production of a tropic acid-N-alkenyl-N- (ss-picolyl) amide, which is characterized in that an acyl tropic acid halide is mixed with allyl (ss-picolyl) amine converts and splits off the 0-acyl group.

           Example: A solution of 32.8 parts by weight of 3-chloromethylpyridine chlorohydrate in 40 parts by weight of water is gradually added to 70 parts by weight of allylamine with shaking, the temperature being kept below 10 ° C. It is shaken for a further two hours at room temperature, then for a further hour at 40 ° C., cooled with ice and saturated with solid potassium hydroxide. The upper layer is separated.

   When the latter is distilled, the unreacted allylamine first passes over under normal pressure and then the allyl (ss-picolyl) amine at 120 ° C. under a pressure of 13 mm Rg.



  To a mixture of 74 parts by weight of allyl (ss-picolyl) amine (bp 13 120 C) and 45 parts by weight of dry pyridine in 250 parts by weight of dry chloroform is crude, from 85 parts by weight of tropic acid by the action of acetyl chloride and subsequent treatment Acetyltropic acid chloride obtained with excess thionyl chloride was gradually added with stirring and ice-water cooling.

   Finally, the mixture is stirred for another hour at normal temperature.



  Then the chloroform solution is diluted with 250 parts by weight of ether and shaken with 3N hydrochloric acid. The weakly Congo acidic solution is heated for one hour on the steam bath, whereby the acetyl group of the reaction product is split off. It is filtered over charcoal and treated with excess concentrated ammonia.

   The precipitated condensation product is taken up in chloroform, the chloroform net getrock and distilled. What remains
