Description

  

  Verfahren zur Herstellung von     4-Amino-benzolsulfonamido-benzol-4'-sulfonacetylamid.       Gegenstand des vorliegenden Patentes  ist ein Verfahren zur Herstellung von       4-Aminobenzolsulfonamido-benzol-4'-sulfon-          acetylamid,    das dadurch gekennzeichnet ist,  dass man ein     BenzoIsulfonamido-benzol-4'-          sulfonacetamid,    das in     4-Stellung    eine durch  Hydrolyse in die     Aminogruppe        überführbare     Gruppe enthält, mit einem     hydrolysierenden          Mittel    behandelt.

       Solehe    in die     Amino-          gruppo        überführbaren        Gruppen    sind z. B.  die     Acylamina-,        Alkylamino-,        Arylamino-,          Aralkylamino-    und die     Azomethin-Gruppe,     der     Isoeyansäureesterrest    (entstanden durch       Ho.fmannschen    Abbau aus     Säureamiden),

      der       Alkylearbaminsäurerest    (entstanden durch       Curtius'        Abbau    aus     Säureamiden)    und     dergl.,          insbesondere    sind     verwendbar    die     Acetyl-          amino-,        Carbalkoxyamino-Verbindungün.     



  Die neue Verbindung soll als Arznei  mittel oder als Zwischenprodukt zur Herstel  lung von Arzneimitteln oder     andern    technisch  wertvollen Verbindungen dienen.  



  Mit Vorteil verwendet man das 4-Acetyl-         amino    -     benzolsulf        onamido    - Benzol -     4'-        sulfon-          acetylamid,    das durch Behandlung von  4 -     Amino-benzolsulf        onamido-benzol-4'-sulf        on-          amid    mit einem     acetylierenden    Mittel erhal  ten wurde.    <I>Beispiel:</I>    32,7 g     4-Amino-benzol-sulfonamiclo-ben-          zol-4'-sulfonamid    werden mit 200 cm' Essig  säureanhydrid zum Sieden erhitzt.

   Nachdem  vollständige Lösung eingetreten ist, wird  während einer weiteren Stunde gekocht und  die     Diacetylverbindung    durch Eingiessen in  Eiswasser ausgeschieden. Der Niederschlag  wird durch Auflösen in     Natriumearbonat-          lösung    und Ausfällen des Filtrates mit Essig  säure ausgeschieden und     gereinigt.    Nach     Um-          kristallisieren    aus verdünntem Alkohol bildet  das Produkt farblose Nadeln, die bei 178   C  schmelzen.

   Es wird anschliessend durch par  tielle     Verseifung    mit     n-Natronlauge    in das       entsprechende        Aminoprodukt    vom     Smp.    20,9    übergeführt.



  Process for the preparation of 4-amino-benzenesulfonamido-benzene-4'-sulfonacetylamide. The present patent is a process for the preparation of 4-aminobenzenesulfonamido-benzene-4'-sulfonacetylamide, which is characterized in that a BenzoIsulfonamido-benzene-4'-sulfonacetamide, which is in the 4-position by hydrolysis in the Amino group convertible group contains, treated with a hydrolyzing agent.

       Sole marriage in the amino group convertible groups are z. B. the acylamino, alkylamino, arylamino, aralkylamino and the azomethine group, the isoeyanic acid ester residue (formed by Ho.fmann's degradation from acid amides),

      the alkylearbamic acid residue (created by Curtius' degradation from acid amides) and the like, especially the acetylamino, carbalkoxyamino compounds can be used.



  The new compound is intended to be used as a medicinal product or as an intermediate product for the production of medicinal products or other technically valuable compounds.



  It is advantageous to use the 4-acetylamino-benzenesulfonamido-benzene-4'-sulfonacetylamide, which was obtained by treating 4-amino-benzenesulfonamido-benzene-4'-sulfonamide with an acetylating agent . <I> Example: </I> 32.7 g of 4-amino-benzene-sulfonamiclo-benzene-4'-sulfonamide are heated to the boil with 200 cm of acetic anhydride.

   After complete solution has occurred, the mixture is boiled for a further hour and the diacetyl compound is eliminated by pouring it into ice water. The precipitate is separated out and purified by dissolving it in sodium carbonate solution and precipitating the filtrate with acetic acid. After recrystallization from dilute alcohol, the product forms colorless needles that melt at 178 ° C.

   It is then converted into the corresponding amino product with a melting point of 20.9 by partial saponification with sodium hydroxide solution.
