Description

  

  Verfahren zur Darstellung einer     cyclischen        Salfonsäureamidrerbindung.       Wie im Hauptpatent angegeben ist, ge  langt man zu gegen Infektionskrankheiten  hoch wirksamen Verbindungen, wenn man  Abkömmlinge     cyclischer        Diamine        herstellt,     die in den beiden ringständigen     Aminogrup-          pen        Benzolsulfonylreste    tragen, deren     p-Stel-          lung    mit dem Stickstoffatom einer stickstoff  haltigen Gruppe verknüpft ist.  



  Gegenstand des vorliegenden Patentes ist  ein     Verfahren    zur     Herstellung    einer     cycli-          schen        Sulfonsäureamidverbindung,    welches  dadurch gekennzeichnet     ist,    dass man 4.     4'-          Diaminodiphenyläther    mit     einem        4-Acetyl-          aminobenzolsulfonsäurehalogenid    umsetzt.

   Die  Umsetzung erfolgt zweckmässig in Gegen  wart eines säurebindenden Mittels, vorzugs  weise     Pyridin.    Die     Abscheidung    des Reak  tionsproduktes erfolgt vorteilhaft unter Ein  giessen der Reaktionsmischung in verdünnte       11Zineralsäure.     



  Der so erhältliche     4.4'-Bis-(4"-acetyl-          aminobenzolsulfonamido)    -     diphenyläther    bil-         det    ein weisses     Kristallpulver,    das nach voll  ständiger     Entwässerung    bei<B>150'</B> schmilzt.  Das neue Produkt soll therapeutische Anwen  dung finden.  



       Beispiel:     20 g 4.     4'-Diaminodiphenyläther    werden  in 100 cm'     Pyridin    gelöst. Die     Lösung    wird  allmählich mit 47 g     4-Acetylaminobenzosul-          fonsäurechlorid    versetzt und     anschliessend     eine     Stunde    auf dem siedenden     RTasserbad          erwärmt.    Durch Einrühren der     Reaktions-          mischung    in 300 am' konzentrierte Salzsäure,  300 cm' Wasser und Eis wird das Reaktions  produkt abgeschieden, abgesaugt und mit  Salzsäure und später mit Wasser ausge  waschen.

   Man     reinigt    den so erhaltenen  4 .     4'-Bis-(4"-acetylaminobenzol-sulfonamido)-          diphenyläther    durch Lösen in Natronlauge       und    Wiederausfällen mit Salzsäure. Die Ver  bindung wird als weisses     Kristallpulver    erhal  ten, das nach vollständiger     Entwässerung    bei  <B>150,</B> schmilzt.



  Process for the preparation of a cyclic sulfonic acid amide compound. As stated in the main patent, compounds that are highly effective against infectious diseases are obtained if derivatives of cyclic diamines are prepared which have benzenesulfonyl radicals in the two ring-attached amino groups whose p-position is linked to the nitrogen atom of a nitrogen-containing group.



  The present patent relates to a process for the production of a cyclic sulfonic acid amide compound, which is characterized in that 4,4'-diaminodiphenyl ether is reacted with a 4-acetyl aminobenzenesulfonic acid halide.

   The reaction is expediently carried out in the presence of an acid-binding agent, preferably pyridine. The reaction product is advantageously separated out by pouring the reaction mixture into dilute cineral acid.



  The 4.4'-bis- (4 "-acetyl-aminobenzene-sulfonamido) -diphenyl ether which can be obtained in this way forms a white crystal powder which, after complete dehydration, melts at <B> 150 '</B>. The new product is intended to find therapeutic applications .



       Example: 20 g of 4'-diaminodiphenyl ether are dissolved in 100 cm 'of pyridine. The solution is gradually mixed with 47 g of 4-acetylaminobenzosulphonic acid chloride and then heated for one hour on the boiling water bath. The reaction product is separated out by stirring the reaction mixture into 300 μm concentrated hydrochloric acid, 300 cm water and ice, filtered off with suction and washed out with hydrochloric acid and later with water.

   The 4 obtained in this way is cleaned. 4'-Bis- (4 "-acetylaminobenzene-sulfonamido) - diphenyl ether by dissolving in sodium hydroxide solution and reprecipitation with hydrochloric acid. The compound is obtained as a white crystal powder which melts at <B> 150 </B> after complete dehydration.
