  Verfahren zur Herstellung eines     acylierten        p-Amino-benzolsulfonamids.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Verstellung eines     aeylierten          p-Airiino-henzolsulfonamids.    Das Verfahren  ist dadurch gekennzeichnet., dass man eine  Verbindung der Formel  
EMI0001.0005     
    auf eine     Verbindun-    der Formel  
EMI0001.0007     
    worin X und Y zwei bei der Reaktion mit  Ausnahme einer in einem von ihnen enthal  tenen     NI1-Gruppe    sich abspaltende Reste und  R einen durch     Verseifimg    in die     Aminogruppe          überführbaren    Rest., wie z.

   B. eine     Acvlamino-          oder        Carbalkoxyaniino-Gruppe,    bedeuten, ein  wirken lässt und in der erhaltenen     Verbin-          dlulg    den Rest R.     dureh        Verseifung    in die       Aminogrul>pe    überführt.  



  Die entstandene neue Verbindung, das     p-          Amino    -     bc,n7o]sulfon-iNT,-(a-n-propoxy-l)ropio-          nylj-ami < 1,    bildet farblose Kristalle vom       Schmelzpunkt    140". Sie lässt sich mit     anor-          ganisehen    oder     org-anisehen    Basen in Salze  überführen. Sie soll therapeutische Verwen  dung finden.  



       Beispiel:          24,4    Teile     p-Carbäthoxyamino    -     henzolsul-          fonamid        werden    in Chlorbenzol mit<B>15</B> Teilen       a-n-1'i-olioxy-propionsäurecllloricl    und 2 Tei  len Kupferpulver versetzt und das     Gemiseh     einige Stunden     zum    Sieden erhitzt.

   Nacll-    her wird das Chlorbenzol mit Wasserdampf       abdestilliert,    der Rückstand in     Sodalösung     <B>,</B>     auin        genommen,        filtriert        und        das        Filtrat        mit          Salzsäure    versetzt.

   Die     Carbäthoxy        verbin-          clung    wird mit verdünnter Natronlauge ver  seift und das entstandene p     Amino-benzolsul-          fon-N1-(a-n-propoxy-propionyl)    -     amid    durch       Umkristallisation        aus    Alkohol     gereinigt,    wor  auf es einen Schmelzpunkt von     140     zeigt.  



  -Man kann die     Kondensation    des     p-Carb-          iithoxyanlillo    -     benzolsulfonamids    mit     a-Prop-          oxy-propionsäurechlorid    anstatt in Chlorben  zol.

   auch in Nitrobenzol unter Zusatz von  Aluminiumchlorid oder in     Py        ridin        dureli-          führen.    Ebensogut Bann man von einer Me  tallverbindung des     p-Carbäthoxyamino    -     ben-          zolsulfonaniids    ausgehen     und    diese mit     a-n-          Propoxy-propionsäureehlorid    umsetzen. Fer  ner kann man     p-Carhäthoxyaniino-benzolsul-          fonainid    auch mit     a-n-Propoxy-propionsäure     in Gegenwart von     Kondensationsmitteln,    z. B.

  Zum gleichen Endprodukt gelangt man  auch, wenn man eine     Metallverbindung    des     a-          n-Propoxy-propionsäureamids    mit einem p  Carbäthox5     amino    -     benzolsulfolialogenid    um  setzt und die erhaltene     Carbäthoxy-verbindung     verseift.



  Process for the preparation of an acylated p-amino-benzenesulfonamide. The subject of the present patent is a process for adjusting an aylated p-Airiino-henzenesulfonamide. The process is characterized in that one has a compound of the formula
EMI0001.0005
    on a compound of the formula
EMI0001.0007
    wherein X and Y are two residues which split off in the reaction with the exception of one in one of them contained NI1 group and R is a residue which can be converted into the amino group by saponification.

   B. an Acvlamino- or Carbalkoxyaniino group, mean, lets act and in the compound obtained the remainder R is converted into the amino group by saponification.



  The resulting new compound, the p-amino-bc, n7o] sulfone-iNT, - (an-propoxy-1) ropionylj-ami <1, forms colorless crystals with a melting point of 140 ". It can be seen with inorganic or Conversion of organic bases into salts for therapeutic use.



       Example: 24.4 parts of p-carbethoxyamino-henzenesulfonamide are mixed in chlorobenzene with 15 parts of a-n-1'i-olioxy-propionic acid chloricl and 2 parts of copper powder and the mixture is heated to the boil for a few hours.

   The chlorobenzene is then distilled off with steam, the residue is taken up in soda solution, filtered and the filtrate is treated with hydrochloric acid.

   The carbethoxy compound is soaped with dilute sodium hydroxide solution and the resulting p-amino-benzenesulfon-N1- (a-n-propoxypropionyl) amide is purified by recrystallization from alcohol, whereupon it has a melting point of 140.



  - You can use the condensation of p-Carb- iithoxyanlillo - benzenesulfonamide with a-Propoxy-propionic acid chloride instead of in chlorobenzene.

   also lead in nitrobenzene with the addition of aluminum chloride or in pyridine dureli. It is just as good to start from a metal compound of p-carbethoxyamino - benzene sulfonaniids and react this with a-n-propoxypropionic acid chloride. Fer ner can p-Carhäthoxyaniino-benzenesulfonainid with a-n-propoxy-propionic acid in the presence of condensing agents, eg. B.

    of phosphorus pentoxide or of phosphorus penta chloride.



  The same end product is also obtained if a metal compound of a-n-propoxypropionic acid amide is reacted with a p carbethox5amino-benzenesulfolialogenide and the resulting carbethoxy compound is saponified.
