Description

  

  Verfahren     zui-    Darstellung von     3-Amino-4-oxy-2'-metliyl-4'-glykolylaminoarsenobenzol-          formaldehydbisulfit.       Im Hauptpatent ist die Darstellung von       4-Ulykolylamitio-3'-amino-4'-oxyarsenobenzol-          foi#maldehydbisulfit    beschrieben.  



  Gegenstand der vorliegenden     Erfindung    ist  ein Verfahren zur Darstellung von     3-Amino-          4-        oxy-2'-in        ethyl-4'-glykolyl        amin        oarsen        obenzol-          formaldehydbisulfit,    welches dadurch gekenn  zeichnet ist, dass man     3-Amino-4-oxy-2'-methyl-          4'-glykolylaminoarsenobenzol    mit Formal  dehydbisulfit umsetzt.  



  Das Endprodukt ist gelb gefärbt, in  Wasser löslich, und eignet sich hervorragend  zur Bekämpfung von     Spirochäten-    und     Try-          panosomenerkrankungen.     



  <I>Beispiel:</I>  28     gr    3 -     Amino    - 4 -     oxy    -     2'-methyl-4'-gly-          kolylaminoarsenobenzolnatrium    (Zusatzpatent  Nr. 153412) werden in 112 cm' Wasser  gelöst und mit einer     .Lösung    von 8,4     gr          Fornialdehydbisulfitriatrium    in 9,5     em3    Wasser    umgesetzt. Die Aufarbeitung der Lösung ist.  dieselbe wie im Beispiel des     lhtuptpatentes.     Das Präparat ist gelb gefärbt und in Wasser  löslich.



  Method for preparing 3-amino-4-oxy-2'-methyl-4'-glycolylaminoarsenobenzene-formaldehyde bisulfite. In the main patent, the preparation of 4-Ulykolylamitio-3'-amino-4'-oxyarsenobenzolfoi # maldehydbisulfit is described.



  The present invention relates to a process for the preparation of 3-amino-4-oxy-2'-in ethyl-4'-glycolyl amine oarsenobenzol- formaldehyde bisulfite, which is characterized in that 3-amino-4-oxy- Reacts 2'-methyl-4'-glycolylaminoarsenobenzene with formaldehyde bisulfite.



  The end product is yellow in color, soluble in water, and is ideal for combating spirochete and trypanosomal diseases.



  <I> Example: </I> 28 gr 3 - amino - 4 - oxy - 2'-methyl-4'-glycolylaminoarsenobenzene sodium (additional patent no. 153412) are dissolved in 112 cm 'of water and mixed with a solution of 8 , 4 gr formaldehyde bisulfite tri-sodium reacted in 9.5 em3 water. Working up the solution is. same as in the example of the main patent. The preparation is yellow in color and soluble in water.
