  Verfahren zur Darstellung von     1-Diäthylaminoäthyl-1   <B>.</B> 2.<B>3.</B>     4-tetrahydro-6-          phenoxychinolin.       Es wurde gefunden,     dass    man zu     tliera-          peutiseli    ausserordentlich wertvollen, spezi  fisch wirksamen, neuen Heilmitteln dadurch  gelangen kann,     dass    man durch     basiselle    Reste  substituierte Amine darstellt, die einen  aromatischen,

       'alizyklischen    oder     hetero-          zyklischen    Rest     äther-    oder     thioätherartig     mit einem dieser zyklischen Reste ein- oder  mehrfach verknüpft enthalten.  



  Gegenstand vorliegender Erfindung ist  nun ein Verfahren zur Darstellung von     1-          Diäthylamino-ä,thyl-l.        2"'   <B>'</B>     3.4-tetrahydro-6-          chenoxychinolin.    Dieses Verfahren ist da  durch gekennzeichnet,     dass    man<B>1.</B> 2.<B>3.</B>     4-          Tetrahydro-6-phenoxychinolin    mit einem     Di-          äthylaminoäthylierungsmittel    zur Umsetzung  bringt, zum Beispiel, indem man die     Aus-          ga#ngsmaterialien    verschmilzt oder in Gegen  wart eines Lösungsmittels zusammen erhitzt.

    Als     Diäthylaminoätliylierungsmittel    kann  man     Diäthylamino-äthylhalogenid,    seine    Salze oder     Diäthylaminoäthyl-p-toluolsulfo-          säureester    verwenden. Die neue Verbindung  stellt ein gelbes, leicht     oxydables   <B>01 vom</B>       Kp   <B>1</B>     222   <B>'</B>dar. Mit Salzsäure, Schwefelsäure,  Salpetersäure und organischen Säuren bildet  sie farblose, in Wasser lösliche Salze. Sie  soll als therapeutisch wertvolles, spezifisch  wirksames Heilmittel Verwendung finden.

    <I>Beispiel:</I>  <B>18,5</B>     gr        p-Aminodiphenyläther,   <B>5</B>     gr'p-          Nit        rodiphenylitlier,   <B>7,5</B>     gr    Arsensäure und  43     cm#    Glyzerin werden auf<B>130</B> bis 140<B>'</B>  erhitzt, dann 14,2     em#    konzentrierte     Sc'hwe-          felsäure        zufliessän    gelassen und die Mischung  acht Stunden auf     140#'    gehalten. Nach     Zu--          gabe    des gleichen Volumens Wasser wird mit  Tierkohle aufgekocht und filtriert.

   Das Fil  trat wird mit     Natriumacetat        versetA    und  das ausgeschiedene     6-Phenoxychinolin    in  Äther aufgenommen.     EA    destilliert unter      <B>1,5</B><U>-mm</U> Druck als helles<B>01</B> bei<B>170'.</B> Durch  Reduktion mit Natrium in Alkohol erhält  man daraus das<B>1.</B>     4,   <B>-</B>     Tetraliydro-6-          phenoxychinolin    als     liellgelbes   <B>01</B> vom     Kp   <B>1,5</B>  <B>197 0.</B>

  Process for the preparation of 1-diethylaminoethyl-1 <B>. </B> 2. <B> 3. </B> 4-tetrahydro-6-phenoxyquinoline. It has been found that extraordinarily valuable, specifically effective, new remedies can be obtained by representing amines which are substituted by basic radicals, which have an aromatic,

       'Contain alicyclic or heterocyclic radical ether- or thioether-like with one of these cyclic radicals linked one or more times.



  The present invention now provides a process for the preparation of 1-diethylamino-a, thyl-l. 2 "'<B>' </B> 3.4-tetrahydro-6-chenoxyquinoline. This process is characterized in that <B> 1. </B> 2. <B> 3. </B> 4- Reacting tetrahydro-6-phenoxyquinoline with a diethylaminoethylating agent, for example by fusing the starting materials or heating them together in the presence of a solvent.

    Diethylaminoethyl halide, its salts or diethylaminoethyl-p-toluenesulfonic acid ester can be used as the diethylaminoethylating agent. The new connection is a yellow, slightly oxidizable <B> 01 of </B> Kp <B> 1 </B> 222 <B> '</B>. With hydrochloric acid, sulfuric acid, nitric acid and organic acids, it forms colorless salts that are soluble in water. It should be used as a therapeutically valuable, specifically effective remedy.

    <I> Example: </I> <B> 18.5 </B> gr p-aminodiphenyl ether, <B> 5 </B> gr'p- nit rodiphenylitlier, <B> 7.5 </B> gr Arsenic acid and 43 cm # glycerine are heated to <B> 130 </B> to 140 <B> '</B>, then 14.2 em # concentrated sulfuric acid are poured in and the mixture is heated to 140 # for eight hours. '    held. After adding the same volume of water, it is boiled with animal charcoal and filtered.

   Sodium acetate is added to the filtrate and the 6-phenoxyquinoline which has separated out is taken up in ether. EA distilled under <B>1,5</B> <U> -mm </U> pressure as light <B> 01 </B> at <B> 170 '. </B> By reduction with sodium in alcohol the <B> 1. </B> 4, <B> - </B> Tetraliydro-6-phenoxyquinoline is obtained therefrom as a slightly yellow <B> 01 </B> with a b.p. <B> 1.5 </B> <B> 197 0. </B>
