Description


  Verfahren zur Herstellung von     p-amino-benzolsulfonyl-a-amino-pyridin-Bz-N-          methylensulfosaurem        Piperazin.    -    Im Hauptpatent ist ein Verfahren zur       Herstellung    von     p-amino-benzolsulfonyl-a-          amino        -pyridin    - Bz     -N'i,-methylensulfosaurem          Hegamethylentetramin    durch     Umsetzung    der  freien Säure mit     Hegamethylentetramin    be  schrieben.  



       Es        wurde    nun     ,gefunden,    dass man ein       therapeutisch    ebenso wertvolles Salz erhält,  wenn man     p-Amino-benzolsulfonyl-a--:amino-          pyridän-Bz-N-methylensuI-fos@äure    in Gegen  wart eines     Alikohals    auf     Piperazin        einwirken     lässt.  



       Beispiel:     8,61 g     Piperazin    werden in 500 cm'       Wasser        gelöst    und allmählich unter Um  rühren eine     Aufschwemmung    von 34,38 g  fein pulverisierter     p-Amino-benzoleulfonyl-a-          amino-pyridin-Bz-N-methylensulfosäure        in     250 cm' eines Alkohols, beispielsweise     Iso-          propylalko#hol,    zugegeben.

   Es erfolgt, gege  benenfalls unter     Erwärmen,    Auflösung und    fast     gleichzeitig        Ausscheidung    von     p-a@mino-          benzo-I        ulfonyl    - a -     amino    -     pyridin    - Bz --N     -          methylensul@osaurem        Piperazin.    Durch     Um-          kristallisation    aus     wässsferigem    Alkohol erhält  man     weisse    Plättchen vom Schmelzpunkt 172        (unter    Zersetzung);

   das     sulfosaure        Piperazin     soll therapeutisch Verwendung finden.
