Description

       

  <B>Verfahren zur Herstellung eines neuen aromatischen</B>     Thioäthers.       Das vorliegende Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen aroma  tischen     Thioäthers,    nämlich des     2,4-Dioxy-5-          sulfo-phenyl-isobutyl-thioäthers.     



  Dieser     Thioäther    hat eine starke Hemm  wirkung auf das Bakterienwachstum sowie  eine gewisse     vermicide    Wirkung und soll als       Chemotherapeuticum    Verwendung finden.  



  Das     erfindungsgemässe    Verfahren zur Her  stellung des neuen aromatischen     Thioäthers     ist, dadurch gekennzeichnet, dass man auf  eine Verbindung der Formel  
EMI0001.0010     
    eine Verbindung der Formel  
EMI0001.0011     
    einwirken lässt, wobei X und Y sich bei der  Reaktion abspaltende Reste bedeuten, und dass  man anschliessend im erhaltenen     Thioäther    mit  einem     Sulfurierungsmittel    die     Sulfogruppe     einführt.  



  Man kann beispielsweise auf ein Metall  salz des     2,4-Dioxy-thiophenols    (X =     Me,    z. B.  Natrium, Kalium usw.) eine Verbindung der  Formel     II    einwirken lassen, in welcher Y ein       Ilalogenatom    oder     einen    andern sich leicht  abspaltenden Rest, wie z. B. einen     Alkyl-    oder       Ai_yl-sulfonyloxyrest,    bedeutet. Es ist weiter  auch möglich, dass     2,4-Dioxy-thiophenol        in    Ge-         genwart    eines basischen Kondensationsmittels  mit einer Verbindung der Formel     II    umzuset  zen.

   Die Einführung der     Sulfogruppe    kann  mit Hilfe von     Oleum    oder von     Halogensulfon-          säuren,    wie z. B.     Chlorsulfonsäure,    erfolgen. ,  Der auf diese Weise erhaltene     2,4-Dioxy-5-          sulfo-phenyl-isobutyl-thioäther    bildet ein Na  triumsalz, das in weissen Blättchen kristalli  siert, die sich bei 325  unter Braunfärbung  zersetzen.  



       Beispiel:     9,1 g     Natrium    werden in 500 cm 3     abs.     Äthanol gelöst. Die Lösung wird mit 50 g     2,4-          Dioxy-thiophenol    versetzt und unter Rühren  50 g     Isobutylbromid    zugegeben. Man     erwärmt     3 Stunden auf dem Dampfbad,     destilliert    das  Äthanol ab, nimmt in Äther auf, behandelt die  ätherische Lösung mit Wasser und destilliert  sie dann nach dem Trocknen im Vakuum.

   Der  so erhaltene, unter 0,06 mm bei<B>113</B> bis<B>1150,</B>  siedende     2,4-Dioxy-phenyl-isobutyl-thioäther     (50 g) wird in 300     em3        abs.    Nitrobenzol ge  löst und unter     Eiskühlung    tropfenweise mit  30 g     Chlorsulfonsäure    versetzt. Man     turbiniert     2     Stunden    bei 18 bis 22 , lässt dann über Nacht  stehen, schüttelt die     Nitrobenzollösung    mit  Wasser aus und engt die     wässrige    Lösung im  Vakuum auf 250     cms    ein.

   Zur Reinigung wird  die Lösung nach dem Klären mit Tierkohle  mit     Natriumchlorid    zwecks Fällung des Na  triumsalzes versetzt. Dieses wird abgesaugt,  mit gesättigter Kochsalzlösung gewaschen, ge  trocknet und einige Male mit     absol.        Äthanol     ausgekocht. Die     äthanolischen    Filtrate werden  eingeengt und gekühlt. So erhält man unge-           fähr    20 bis 25 g     Natriumsalz    des     2,4-Dioxy-5-          sulfo-phenyl-isobutyl-thioäthers    in Form wei  sser Blättchen, die sich bei 325  unter Braun  färbung zersetzen.

   Das Salz löst sich sehr  leicht in kaltem Wasser, leicht in wasserhal  tigem Methanol, Äthanol und Aceton.



  <B> Process for the production of a new aromatic </B> thioether. The present patent relates to a process for the production of a new aromatic thioether, namely 2,4-dioxy-5-sulfo-phenyl-isobutyl-thioether.



  This thioether has a strong inhibitory effect on bacterial growth as well as a certain vermicidal effect and is said to be used as a chemotherapeutic.



  The process according to the invention for preparing the new aromatic thioether is characterized in that a compound of the formula
EMI0001.0010
    a compound of the formula
EMI0001.0011
    can act, where X and Y are radicals split off during the reaction, and that the sulfo group is then introduced into the thioether obtained with a sulfurizing agent.



  For example, a compound of the formula II in which Y is an halogen atom or another easily split off radical can act on a metal salt of 2,4-dioxy-thiophenol (X = Me, e.g. sodium, potassium, etc.) such as B. is an alkyl or Ai_yl-sulfonyloxy radical. It is furthermore also possible to react 2,4-dioxy-thiophenol with a compound of the formula II in the presence of a basic condensing agent.

   The sulfo group can be introduced with the aid of oleum or halosulfonic acids, such as. B. chlorosulfonic acid. , The 2,4-dioxy-5-sulfo-phenyl-isobutyl-thioether obtained in this way forms a sodium salt which crystallizes in white flakes which decompose at 325 with a brown color.



       Example: 9.1 g sodium are in 500 cm 3 abs. Dissolved ethanol. 50 g of 2,4-dioxy-thiophenol are added to the solution, and 50 g of isobutyl bromide are added with stirring. It is heated for 3 hours on the steam bath, the ethanol is distilled off, taken up in ether, the ethereal solution is treated with water and then, after drying, it is distilled in vacuo.

   The 2,4-dioxy-phenyl-isobutyl-thioether (50 g), boiling below 0.06 mm at <B> 113 </B> to <B> 1150, is dissolved in 300 cubic meters of abs. Dissolved nitrobenzene and treated dropwise with 30 g of chlorosulfonic acid while cooling with ice. Turbine is carried out for 2 hours at 18 to 22, then left to stand overnight, the nitrobenzene solution is shaken out with water and the aqueous solution is concentrated in vacuo to 250 cms.

   To clean the solution, after clarifying with animal charcoal, sodium chloride is added to precipitate the sodium salt. This is filtered off with suction, washed with saturated sodium chloride solution, dried and a few times with absol. Boiled ethanol. The ethanolic filtrates are concentrated and cooled. This gives about 20 to 25 g of the sodium salt of 2,4-dioxy-5-sulfo-phenyl-isobutyl-thioether in the form of white flakes which decompose at 325 to turn brown.

   The salt dissolves very easily in cold water, easily in water-containing methanol, ethanol and acetone.
