Description

  

  Verfahren zur Darstellung einer     N-substituierten    Verbindung der     Pyridonreihe.       Es wurde gefunden, dass man zu einer       RT-substituierten    Verbindung der     Pyridonreihe     gelangen kann, wenn man einen Ester des       Diäthylaminoäthanols    an     Isochinolin    anlagert  und das     Additionsprodukt    oxydiert.  



  Das entstandene N -     Diäthylaminoäthyl-          isochinolon    ist ein gelbes Öl; es siedet bei  175--17$" unter 1,5 mm Druck. Es ist un  löslich in     Wasser,''gut    löslich in organischen  Lösungsmitteln, sowie in Säuren. Das     Pikrat     schmilzt bei     162-1641'.     



  Die neue Base soll für therapeutische  Zwecke Verwendung finden.    <I>Beispiel:</I>  Äquivalente Mengen     Isochinolin    und     Chlor-          äthyldiäthylaminchlorhydrat    werden auf 125    erhitzt, bis das Reaktionsprodukt wasserlös  lich ist.

   30 Teile des so erhaltenen     Diäthyl-          aminoisochinoliniumohlorides    werden in Was  ser gelöst und nach Zusatz von 30 Teilen       Kaliumhydroxyd    mit einer     wässerigen    Lösung    von 66 Teilen     Kaliumferricyanid    versetzt  Nach erfolgter Oxydation wird das gebildete       galiumferrocyanid        abfiltriert    und die Base  durch Zugabe von Alkali als Öl vollständig  abgeschieden.

   Durch Destillation erhält man  das     N-Diäthylaminoäthylisochinolon    in reiner  Form:  Für die Anlagerung an     Isochinolin    kön  nen an Stelle des     Chlorides    auch andere  Ester des     Diäthylaminoäthanols,    zum Beispiel  das     Bromid    oder aromatische     Sulfosäureester,     Verwendung finden. Ferner lässt sich die  Oxydation der     quaternären    Base auch auf  andere Weise, zum Beispiel auf elektrolyti  schem Wege, durchführen.



  Process for the preparation of an N-substituted compound of the pyridone series. It has been found that an RT-substituted compound of the pyridone series can be obtained if an ester of diethylaminoethanol is added to isoquinoline and the addition product is oxidized.



  The resulting N - diethylaminoethyl isoquinolone is a yellow oil; it boils at $ 175--17 "under 1.5 mm pressure. It is insoluble in water," readily soluble in organic solvents and acids. The picrate melts at 162-1641 '.



  The new base will be used for therapeutic purposes. <I> Example: </I> Equivalent amounts of isoquinoline and chloroethyl diethylamine chlorohydrate are heated to 125 until the reaction product is water-soluble.

   30 parts of the diethyl aminoisoquinolinium chloride obtained in this way are dissolved in what water and, after the addition of 30 parts of potassium hydroxide, an aqueous solution of 66 parts of potassium ferricyanide is added.

   The N-diethylaminoethylisoquinolone is obtained in pure form by distillation: for the addition to isoquinoline, other diethylaminoethanol esters, for example bromide or aromatic sulfonic acid esters, can be used instead of the chloride. Furthermore, the oxidation of the quaternary base can also be carried out in other ways, for example in an electrolytic way.
