Description

  

      Verfahren   <B>zur</B>     Herstellung        eines        diquartären        Diammoninmsalzes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung     eines        _diquartären          Diammoniumsalzes.    Das Verfahren     ist    da  durch gekennzeichnet,

   dass man 1     Mol        Mono-          thiohydrochinon    mit 2     Mol    eines     y-Dimethyl-          amino-propylhalogenids    umsetzt und auf das  erhaltene     1-(y-Dimethylamino-propoxy)-4-(y-          dimethylamino-propylmercapto)-benzol    2     Mol          Äthyljodid        einwirken    lässt.  



  Die erhaltene neue     Verbindung,    das     Di-          äthojodid    des     1-(y-Dimethylamino-propoxy)-          4-        (y-dimethylamino    -     propylmercapto)    - Benzols,  schmilzt bei 198 . Sie soll als Arzneimittel Ver  wendung finden.  



  <I>Beispiel:</I>  12,6 Teile     Monothiohydrochhion,    30,0 Teile       y-Dimethylamino-propylchlorid    und 100     Vo-          lumteile        abs.        Toluol    werden in einer Atmo  sphäre von reinem Stickstoff auf 40-50  er  wärmt und dann unter Rühren mit     einer     Suspension von 11,3 Teilen in     Toluol    fein  gemahlenem     Natriumamid    in kleinen Portio  nen versetzt.

   Anschliessend rührt man noch  2 Stunden bei 40-50  und 4     Stunden    unter  Kochen am     Rückfluss.    Nach dem Abkühlen  setzt man unter Rühren so viel     2n-Salzsäure     zu, dass die wässerige Schicht kongosauer  bleibt, trennt die     Toluolschicht    ab und wäscht  mit wenig Wasser nach.

   Die vereinigte salz  saure und wässerige Lösung wird mit Äther  gewaschen, dann durch Filtration     (event.    mit       etwas        Tierkohle)        geklärt        und        mit        30        %        iger     Natronlauge stark     mimosaalkalisch    gestellt.

    Die ausgeschiedene Base wird durch zweimali-    ges     Ausschütteln    in Äther     aufgenommen.     Nach Trocknen der Ätherlösung mit Kalium  carbonat und     Abdestillieren    aller flüchtigen  Teile (zuletzt bei 90-100  unter 1     mm    Druck)  erhält man das     1-(y-Dimethylamino-propoxy)-          4-    (<B>),</B>     -dimethylamino-propylmercapto)-benzol     als Öl, das     nötigenfalls    noch durch Filtration  mit Kohle oder ähnlichen     Hilfsmitteln        geklärt     und etwas aufgehellt wird.  



  8 Teile dieser Base werden in 50     Volum-          teilen    Aceton gelöst, unter gelegentlichem  Kühlen     allmählich        mit    15 Teilen     Äthyljodid     versetzt und anschliessend einige     Stunden    un  ter     Rückfliess    gekocht.

   Nach dem Abkühlen  saugt man das     Di-äthojodid    des     1-(y-Dime-          thjamino-propoxy        )-4-(y-dimethylamino-pro-          pylmercapto)-benzols    ab und     kristallisiert    es       gewünschtenfalls    aus Methanol unter Zusatz  von etwas     Butanon    um. Schmelzpunkt 198 .



      Process <B> for </B> production of a diquartary diammonine salt. The present patent is a process for the preparation of a _diquartary diammonium salt. The procedure is characterized by

   that 1 mol of monothiohydroquinone is reacted with 2 mol of a γ-dimethylamino-propyl halide and 2 mol of ethyl iodide are allowed to act on the 1- (γ-dimethylamino-propoxy) -4- (γ-dimethylamino-propylmercapto) benzene.



  The new compound obtained, the diethoiodide of 1- (γ-dimethylamino-propoxy) -4- (γ-dimethylamino-propylmercapto) -benzene, melts at 198. It should be used as a medicinal product.



  <I> Example: </I> 12.6 parts of monothiohydrochloride, 30.0 parts of γ-dimethylamino-propyl chloride and 100 parts by volume of abs. Toluene is heated in an atmosphere of pure nitrogen to 40-50 and then mixed with stirring with a suspension of 11.3 parts in toluene finely ground sodium amide in small Portio NEN.

   The mixture is then stirred for a further 2 hours at 40-50 and 4 hours with refluxing. After cooling, enough 2N hydrochloric acid is added with stirring that the aqueous layer remains acidic to the Congo, the toluene layer is separated off and washed with a little water.

   The combined hydrochloric acid and aqueous solution is washed with ether, then clarified by filtration (possibly with a little animal charcoal) and made strongly mimosa-alkaline with 30% sodium hydroxide solution.

    The precipitated base is taken up in ether by shaking twice. After drying the ethereal solution with potassium carbonate and distilling off all volatile components (finally at 90-100 under 1 mm pressure), 1- (γ-dimethylamino-propoxy) -4- (<B>), </B> -dimethylamino is obtained -propylmercapto) -benzene as an oil, which if necessary is clarified and lightened somewhat by filtration with charcoal or similar aids.



  8 parts of this base are dissolved in 50 parts by volume of acetone, 15 parts of ethyl iodide are gradually added with occasional cooling and then refluxed for a few hours.

   After cooling, the di-ethyodide of 1- (γ-dimethylamino-propoxy) -4- (γ-dimethylamino-propylmercapto) -benzene is suctioned off and, if desired, it is recrystallized from methanol with the addition of a little butanone. Melting point 198.
