  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.



  Process for the preparation of p-aminobenzenesulfonyl-a-aminopyridine-Bz-N-methylensulfosaurem piperazine. - In the main patent, a process for the preparation of p-amino-benzenesulfonyl-a-amino-pyridine - Bz -N'i, -methylensulfosaurem hegamethylenetetramine by reacting the free acid with hegamethylenetetramine be written.



       It has now been found that a therapeutically equally valuable salt is obtained if p-amino-benzenesulfonyl-a-: aminopyridän-Bz-N-methylene-sulfonyl-acid is allowed to act on piperazine in the presence of an alico neck.



       Example: 8.61 g of piperazine are dissolved in 500 cm 'of water and gradually stirring a suspension of 34.38 g of finely powdered p-amino-benzenesulfonyl-a-aminopyridine-Bz-N-methylene sulfonic acid in 250 cm' of a Alcohol, for example isopropyl alcohol, added.

   It takes place, if necessary with heating, dissolution and almost at the same time excretion of p-a @ minobenzo-lulfonyl - a - amino - pyridine - Bz --N - methylensulf @ osaurem piperazine. Recrystallization from aqueous alcohol gives white platelets with a melting point of 172 (with decomposition);

   the sulfonic acid piperazine is said to be used therapeutically.
