Description

  

  Verfahren zur Darstellung von     2,4-Bis-(a-diäthylamino-a-pentylamino)-          pheiiyleyclohexylä,ther.       Es wurde gefunden,     dass    man zu thera  peutisch. ausserordentlich wertvollen, spezi  fisch wirksamen, neuen Heilmitteln dadurch  gelangen kann,     dass    man durch basische Reste  substituierte Amine darstellt, die einen  aromatischen,     alizyklischen    oder     hetero-          zyklisehen    Rest     äther-    oder     thioä.therartig     mit einem dieser zyklischen Reste ein- oder  mehrfach verknüpft enthalten.  



  Gegenstand vorliegender Erfindung ist  nun ein Verfahren zur Darstellung von     2,4-          Bis-#a-diä,thylamino-ö-pentylamino)        -phenyl-          cyclohexyläther.    Dieses Verfahren ist da  durch gekennzeichnet,     dass'man        2',4-Diamino-          phenyle,yclohexyläther    mit einer in     b-Stel-          lung    reaktionsfähigen     a-Diäthylamiuopentan-          verbindung    zur Umsetzung bringt, zum Bei  spiel indem man die Ausgangsmaterialien  verschmilzt oder in Gegenwart eines Lö  sungsmittels zusammen erhitzt.

   Als     a-Di-          ätliylaminopenta-nverbiuclung    verwendet man    zweckmässig     a-Diätllylamino-ö-brompentan     oder seine Salze.  



  Die neue Verbindung stellt ein helles<B>01</B>  vom     Kp   <B>1</B> 240<B>1</B> dar. Mit Salzsäure,     Sellwe-          felsäure,    Salpetersäure und organischen Säu  ren bildet sie farblose, in Wasser lösliche  Salze. Sie soll als therapeutisch wertvolles,  spezifisch wirksames Heilmittel Verwendung  finden.  



  <I>Beispiel:</I>  41     gr        2,4-Diaminophenyleyelohexyläther          (Kp   <B>1 181',</B> gewonnen aus     Cyclollexanol-          kalium    und     -2,4-Dinitrochlorbenzol    und Re  duktion der entstandenen     Dinitroverbindung),     <B>32</B>     gr        a-Diäthylamino-b-brompentanhydro-          bromid    und<B>25</B>     em#    Wasser werden acht Stun  den bei 120 bis     lssO'    verschmolzen. Das Re  aktionsprodukt wird in verdünnter Salzsäure  aufgenommen, durch Alkali in Freiheit ge  setzt und in Äther aufgenommen.

   Nach dem      Trocknen und Verdampfen des Äthers wird  durch Fraktionieren von überschüssigem     2,4-          Dia.minophenylcyclohexyläther    getrennt. Der  neue     2,4-Bis-(a-diäthylamino-b-pentylaming)-          phenyleyelollexyläther    destilliert unter<B>1</B> mm  Druck als gelbes<B>-01</B> bei 240'. Sein schwach  gelb gefärbtes     Hydroe'hlorid    ist     hygrosko-          pisch.  



  Process for the preparation of 2,4-bis (a-diethylamino-a-pentylamino) - pheiiyleyclohexylä, ether. It was found to be too therapeutic. Extraordinarily valuable, specifically effective, new remedies can be obtained by representing amines which are substituted by basic radicals and which contain an aromatic, alicyclic or heterocyclic radical ether-like or thio-ether-like with one of these cyclic radicals linked one or more times.



  The present invention now relates to a process for the preparation of 2,4-bis- # a-diä, thylamino-ö-pentylamino) -phenyl-cyclohexyl ether. This process is characterized in that 2 ', 4-diaminophenyls, cyclohexyl ethers are reacted with an α-diethylamino pentane compound which is reactive in the b-position, for example by fusing the starting materials or in the presence of one Solvent heated together.

   A-diethylaminopentane or its salts are expediently used as a-diethylaminopentane compound.



  The new compound is a light <B> 01 </B> with a bp <B> 1 </B> 240 <B> 1 </B>. It forms colorless with hydrochloric acid, sellwellic acid, nitric acid and organic acids , salts soluble in water. It should be used as a therapeutically valuable, specifically effective remedy.



  <I> Example: </I> 41 g of 2,4-diaminophenyleyelohexyl ether (bp <B> 1 181 ', </B> obtained from cyclollexanol potassium and -2,4-dinitrochlorobenzene and reduction of the resulting dinitro compound), < B> 32 </B> gr a-diethylamino-b-bromopentane hydrobromide and <B> 25 </B> em # water are fused for eight hours at 120 to lssO '. The reaction product is taken up in dilute hydrochloric acid, set free by alkali and taken up in ether.

   After drying and evaporation of the ether, excess 2,4-Dia.minophenylcyclohexyl ether is separated by fractionation. The new 2,4-bis- (a-diethylamino-b-pentylamine) - phenyleyelol xyl ether distilled under <B> 1 </B> mm pressure as a yellow <B> -01 </B> at 240 '. Its pale yellow hydrochloride is hygroscopic.
