Description

  

  Verfahren zur Darstellung einer     Sulfonsäureamidverbindung.       Es wurde gefunden, dass die     Acylamino-          benzolsufonsäureamide,    deren     Acylrest    min  destens 5     Kohlenstoffatome    enthält, thera  peutisch, im besonderen gegen     Streptokokken-          infektionen    gut wirksame Produkte darstellen.  



  Gegenstand des vorliegenden Patentes  ist ein Verfahren zur Darstellung einer     Sul-          fonsäureamidverbindung,    welches dadurch ge  kennzeichnet ist, dass man eine Verbindung,  die sich von der     Phenylessigsäure    dadurch  unterscheidet, dass sie an Stelle der     OH-          Gruppe    einen reaktionsfähigeren     Substituenten     besitzt, auf     4-Aminobenzolsulfonsäureamid     einwirken lässt. Als reaktionsfähige Abkömm  linge der     Phenylessigsäure    kommen ihre Ha  logenide, im besonderen ihr Chlorid, ferner ihre  Ester und ihr     Anhydrid    in Betracht.

   Bei  Verwendung der     Halogenide    arbeitet man  zweckmässig in Gegenwart eines säurebinden  den Mittels, vorzugsweise     Pyridin.    Die Ab  scheidung des Umsetzungsproduktes aus der  Reaktionsmischung kann in an sich üblicher    Weise, zum Beispiel durch Behandeln des  Reaktionsproduktes mit Wasser oder ver  dünnter Säure erfolgen. Nach     Umkristalli-          sieren    des Rohproduktes, zum Beispiel aus  Methanol erhält man     das        4-Phenylacetyl-          benzolsulftinsäureamid    in farblosen Kristallen  vom Schmelzpunkt<B>2060.</B> Es ist in Wasser  und verdünnten Säuren unlöslich und soll  therapeutische Anwendung finden.  



  <I>Beispiel:</I>  17,2 g     4-Aminobenzolsulfonsäureamid    wer  den in 50 cm'     Pyridin    gelöst und mit 16 g       Phenylessigsäurechlorid    versetzt. Nach halb  stündigem Erhitzen auf dem Wasserbad wird  in verdünnte kalte Salzsäure gegossen, der  Niederschlag abgesaugt, mit Salzsäure und  Wasser gewaschen und aus Methanol um  kristallisiert. Man erhält das     4-Phenylacetyl-          amino-benzolsulfonsäureamid    in farblosen Kri  stallen vom Schmelzpunkt<B>2060,</B>



  Process for preparing a sulfonic acid amide compound. It has been found that the acylamino-benzenesulfonic acid amides, the acyl radical of which contains at least 5 carbon atoms, are therapeutically effective products, in particular against streptococcal infections.



  The subject of the present patent is a process for the preparation of a sulphonic acid amide compound, which is characterized in that a compound which differs from phenylacetic acid in that it has a more reactive substituent instead of the OH group is placed on 4-aminobenzenesulphonic acid amide can act. Its halides, in particular its chloride, and also its esters and anhydride come into consideration as reactive derivatives of phenylacetic acid.

   When using the halides, it is expedient to work in the presence of an acid-binding agent, preferably pyridine. The separation of the reaction product from the reaction mixture can be carried out in a conventional manner, for example by treating the reaction product with water or dilute acid. After recrystallization of the crude product, for example from methanol, the 4-phenylacetylbenzenesulftinamide is obtained in colorless crystals with a melting point of 2060. It is insoluble in water and dilute acids and is said to be of therapeutic use.



  <I> Example: </I> 17.2 g of 4-aminobenzenesulfonic acid amide are dissolved in 50 cm of pyridine and mixed with 16 g of phenylacetic acid chloride. After half an hour of heating on the water bath, it is poured into dilute cold hydrochloric acid, the precipitate is filtered off with suction, washed with hydrochloric acid and water and recrystallized from methanol. The 4-phenylacetylamino-benzenesulfonic acid amide is obtained in colorless crystals with a melting point of <B> 2060 </B>

PATENTANSPRUCH: Verfahren zur Darstellung einer Sulfon- säureamidverbindung, dadurch gekennzeich net, dass man eine Verbindung, die sich von der Phenylessigsäure dadurch unterscheidet, dass sie an Stelle der OH-Gruppe einen re aktionsfähigeren Substituenten besitzt, auf 4-Aminobenzeisuifonsäureamid einwirken lässt. Das so erhältliche 4-Phenylacetylamino- benzolsulfonsäureamid bildet farblose Kri stalle vom Schmelzpunkt 206 , die in Wasser und verdünnten Säuren unlöslich sind. UNTERANSPRUCH: 1. Claim: Process for the preparation of a sulfonic acid amide compound, characterized in that a compound which differs from phenylacetic acid in that it has a more reactive substituent in place of the OH group is allowed to act on 4-aminobezisulfonic acid amide. The 4-phenylacetylaminobenzenesulphonic acid amide thus obtainable forms colorless crystals with a melting point of 206, which are insoluble in water and dilute acids. SUBClaim: 1. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man Phenylessig- säurechlorid verwendet und in Gegenwart eines säurebindenden Mittels arbeitet. 2. Verfahren nach Patentanspruch und Un teranspruch 1, dadurch gekennzeichnet, dass als säurebindendes Mittel Pyridin verwendet wird. Process according to patent claim, characterized in that phenylacetic acid chloride is used and an acid-binding agent is used. 2. The method according to patent claim and un teran claim 1, characterized in that pyridine is used as the acid-binding agent.
