Description

  

  Verfahren zur Darstellung einer     Aminobenzolsulfonsäureamidverbindung.       Gemäss Angaben des     Hauptpatentes    sind  gewisse     Aminoacyl-    und     Oxyacylaminobenzol-          sulfonsäureamide,    sowie deren     Substitutions-          produkte    durch ihre Wirkung gegen bakterielle  Infektionskrankheiten ausgezeichnet.  



  Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung von     Phenoxy-          acetylaminobenzol-4-sulfonsäureamid,    welches  dadurch gekennzeichnet ist, dass man auf     4-          Aminobenzolsulforisäureamid    ein für     Acylie-          rungszwecke    geeignetes Derivat der     Phenoxy-          essigsäure    einwirken lässt. Als Derivate der       Phenoxyessigsäure    kommen in erster Linie  das     Phenoxyessigsäurearibydrid    und das     Phen-          oxyessigsäurechlorid    in Betracht.

   Bei Ver  wendung des Chlorids wird zweckmässig ein       salzsäurebindendes    Mittel, z. B.     Natrium-          acetat,    der Reaktionsmischung zugesetzt. Die  Umsetzung erfolgt zweckmässig in Gegenwart  von Wasser und unter Erwärmen. Das so  erhältliche     Phenoxyacetylaminobenzol-4-sul-          fonsäureamid    bildet farblose Kristalle vom    Schmelzpunkt 205 0. Es soll therapeutische  Anwendung finden.    <I>Beispiel:</I>  20,8g Hydrochlorid des     4-Aminobenzol-          sulfonsäureamids    werden in 200     eins.    Wasser  gelöst und 17 g     Phenoxyessigsäurechlorid    zu  gegeben.

   Die Mischung wird unter Rühren  auf dem Wasserbad erwärmt und die kongo  saure Reaktion durch allmähliche Zugabe von  festem     Natriumacetat    abgestumpft. Das aus  fallende     Phenoxyacetylarninobenzol-4-sulfon-          säureamid    wird abgesaugt. Zur Reinigung  von etwas beigemengter     Phenoxyessigsäure          wird        es        mit        kalter    5     %iger        Natriumcarbonat-          lösung    ausgezogen. Es schmilzt bei 205 0.



  Process for preparing an aminobenzenesulfonic acid amide compound. According to the main patent, certain aminoacyl- and oxyacylaminobenzenesulfonic acid amides, as well as their substitution products, are distinguished by their effectiveness against bacterial infectious diseases.



  The subject of the present patent is a process for the preparation of phenoxyacetylaminobenzene-4-sulfonic acid amide, which is characterized in that a derivative of phenoxyacetic acid suitable for acylation purposes is allowed to act on 4-aminobenzenesulfonic acid amide. Phenoxyacetic acid aribydride and phenoxyacetic acid chloride are primarily suitable as derivatives of phenoxyacetic acid.

   When using the chloride, a hydrochloric acid binding agent such. B. sodium acetate, added to the reaction mixture. The reaction is expediently carried out in the presence of water and with heating. The phenoxyacetylaminobenzene-4-sulphonic acid amide which can be obtained in this way forms colorless crystals with a melting point of 205 0. It is said to be of therapeutic use. <I> Example: </I> 20.8 g of hydrochloride of 4-aminobenzenesulfonic acid amide become one in 200. Dissolved water and added 17 g of phenoxyacetic acid chloride.

   The mixture is heated on the water bath while stirring and the Congo acidic reaction is blunted by the gradual addition of solid sodium acetate. The phenoxyacetylarninobenzene-4-sulfonic acid amide which precipitates is filtered off with suction. To clean some of the added phenoxyacetic acid, it is extracted with cold 5% sodium carbonate solution. It melts at 205 0.
