Description


  



  Verfahren zur Herstellung neuer N-substituierter Piperidine
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung neuer N-substituierter Piperidine der Formel I
EMI1.1     
 in welcher A eine Alkylenbrücke mit 1-3 Kohlenstoffatomen, B eine Alkylenbrücke mit 2-3 Kohlenstoffatomen, R und R'niedere Alkylgruppen oder R und   R'zusammen mit dem    N-Atom einen   hetero-    cyclischen Rest,   R"Wasserstoff    oder eine entweder in 2-Stellung oder in   3-Stellung    des Piperidinringes befindliche niedere Alkylgruppe und R1 eine gegebenenfalls substituierte Phenylgruppe bedeuten, das dadurch gekennzeichnet ist, dass eine   Piperidinver-    bindung der Formel II
EMI1.2     
 mit einer Verbindung der Formel III
EMI1.3     
 in welcher X ein Chlor-,

   Brom-oder Jodatom bedeutet, in Gegenwart mindestens eines   Siquivalentes    eines Säureakzeptors umgesetzt wird.



   Erfindungsgemäss herstellbare Verbindungen können als aktive Bestandteile   pharmazeutischer Prä-    parate verwendet werden, die menschlichen Organismen zur Verbesserung der Blutzirkulation in den   Herzgefässen und    der Funktion der Herzgefässe zugeführt werden können, falls diese beeinträchtigt sind.



  Dar ber hinaus zeigen erfindungsgemäss herstellbare Verbindungen eine   antiatheroscierotische    Wirkung in menschlichen Organismen und potenzieren die antihypertensive Wirkung der Veratrum-alkaloide, wie durch klinische Versuche festgestellt werden konnte.



   Erfindungsgemäss herstellbare Verbindungen stellen in Form der   freien Base entweder Flüssig-    keiten hohen Siedepunktes oder weisse kristalline Feststoffe mit niedrigem Schmelzpunkt dar, sind in Wasser unlöslich, löslich in wässrigen Mineralsäuren oder organischen Säuren, wobei aus diesen erhaltenen wässrigen Lösungen durch Verdampfung des Wassers die Säureadditionssalze erhalten werden können, und sind in polaren und unpolaren L¯sungsmitteln, wie beispielsweise niedrigen aliphatischen Alkoholen, Chloroform, Benzol und   Petroläther,    löslich.



   Die Strukturformel der einfachsten erfindungsgemäss herstellbaren Verbindung, nämlich des 4-Benzyl-1-(¯-dimethylaminoÏthyl)-piperidns, ist
EMI1.4     

Der Piperidinring kann ebenso wie die   Phenyl-    alkylgruppe   RA-niedere Alkylgruppen als Substi-      tuenten    aufweisen. Solche Substituenten im   Piperidin-    ring aufweisende Verbindungen stellen vollkommene   Aquivalente    von im   Pyridmnng unsubstituierten Ver-    bindungen dar. 



     Erfinduogsgemäss    herstellbare   N- (Dialkylamino-    alkyl)-piperidine werden auch als   4-Phenylalkyl-1-      (dialkylaminoalky !)-piperidine bezeichnet    und Beispiele für solche Verbindungen sind
4-p-ChlorphenylÏthyl-1-(¯-diisopropyl   aminoäthyl)-piperidin,   
4-(3,4-MethylendioxyphenylÏthyl)   1-(γ-piperidinopropyl)-piperidin,       4- (3,    4,   5-Trimethoxy-phenyläthyl)-3-äthyl-      
1- (, B-diäthylaminoäthyl)-piperidin,
4-(α-Phenylpropyl)-1 -(γ-pyrrolidinopropyl)-    piperidin,
4-(¯-Phenylpropyl)-1-(¯-diÏthylaminopropyl) piperidin,    4-(α -PhenylÏthyl)-1 -(¯-piperidinopropyl)-    piperidin.



   Die Säureadditionssalze erfindungsgemäss herstellbarer Verbindungen können in   iiblicher    Weise durch Umsetzung der freien Basen mit den   gebräuch-    lichen anorganischen Säuren, z. B. SalzsÏure, BromwasserstoffsÏure, JodwasserstoffsÏure, SchwefelsÏure oder Phosphorsäure, oder den gebräuchlichen organischen SÏuren, wie z. B. EssigsÏure, GerbsÏure, ZitronensÏure, MalonsÏure, ¯thansulfonsÏure, Cyclohexylsulfaminsäure und dergleichen hergestellt werden. Diese Salze stellen völlige Äquivalente der freien Basen dar und sind lediglich besonders geeignete Verabreichungsformen.

Eine Lösung von Dimethylaminoäthylchlorid, welche aus 180 g (1, 25 Mol) Dimethylaminoäthyl  chlorid-hydrochlorid    erhalten wurde, in Xylol, wurde tropfenweise ei. ner auf Rückfluss erhitzten Suspension von 175 g (1, 0 Mol) 4-Benzylpiperidin, 104 g (0, 75 Mol) Kaliumcarbonat und 80 g (0, 75 Mol) Natriumcarbonat in 250 cm3 Xylol zugesetzt. Die erhaltene AufschlÏmmung wurde 20 Stunden auf Rückfluss erhitzt, gekühlt, worauf so lange Wasser r zugesetzt wurde, bis alle anorganischen Salze in L¯sung gegangen waren. Die wässrige Schicht wurde sodann verworfen und die Xylollösung eingeengt.



  Der erhaltene ölige Rückstand wurde destilliert, wobei entsprechend einer 53, 5    /oigen    Ausbeute 132 g 4-Benzyl-1-   (} 5-dimethylaminoäthyl)-piperidin bei    einem Siedepunkt von Kp =   110-114°C    bei 0, 1 mm Hg und einem Brechungsindex n24D = 1, 5160 erhalten wurden.

Anschliessend wurde gekühlt und filtriert, worauf das Filtrat im Vakuum eingeengt wurde. Der Rückstand wurde hierauf mit Äther verdünnt, der erhaltene Niederschlag abfiltriert und das Filtrat im Vakuum eingeengt. Bei Vakuumdestillation wurde eine geringe Menge eines Vorlaufes und, entsprechend einer Ausbeute von 31% der Theorie, 12, 3 g   4-Benzyl-1-(,-dimethylamino-      äthyl)-piperidin    erhalten.

   Das 4-Benzyl-l-   B-dimethyl-      aminoäthyl)-piperidin    besass einen Siedepunkt Kp = 135-140  C bei 0, 5 mm Hg und einen Brechungsindex   n 24    =   1,    5167.
