  Verfahren zur Darstellung von     3-(Diozypropyl-ogyäthyl)-amino-4-oay-3'-ogy-4'-          amino-arsonobenzol-formaldehydbisulfitnatrium.       Durch die schweizerische     Patentschrift     Nr. 157187 ist bekannt, dass sich     Amino-          arsenobenzole    durch     Umsetzung        mit        Alkylen-          oxyden    und     Formaldehydbisulfitnatrium    zu       Oxyalkylaminoarsenobenzol    -     formaldehydbi-          sulfitverbindungen        kondensieren.    lassen.  



  Es wurde nun gefunden, dass man     3-(Di-          oxypropyl-        oxyäthyl)        -amino-4-oxy-3'-        oxy-4'-          amino    -     arsenobenzol    -     formaldehydbisulfit-          natrium    in der Weise herstellen kann, dass  man     3-(Dioxypropyl-oxyäthyl)

  -amino-4-oxy-          benzol-l-arsineäure    mit     3-O@xy-4-aminobenzol-          1.-arsinsäure    zu dem entsprechenden asymme  trischen     Arsenobenzolderivat    kondensiert     und          letzteres    mit     Formaldehydbisulfitnatrium          umsetzt.     



  Die neue     Verbindung    stellt ein     gelbes     Pulver dar, welches in Wasser leicht löslich  und in Methylalkohol, Äthylalkohol, Äther  und Aceton unlöslich ist. Sie soll als Arznei-    mittel, insbesondere als     Antisyphilitikum          Verwendung    finden.  



  <I>Beispiel:</I>  35,1 g     3-(Dioxypropyl-oxyäthyl)-amino-          4-oxybenzol-l-arsinsäure,    dargestellt nach der  deutschen Patentschrift Nr. 618447, Beispiel  3, und 23,3 g     3-Oxy-4-aminobenzol-l-arsin-          säure,    erhältlich nach der deutschen Patent  schrift Nr. 244166, werden in Salzsäure ge  löst und mittels     unterphosphoriger    Säure     in          Gegenwart    von     Jodkali    zum salzsauren     3-          (Dioxypropyl    -     oxyäthyl)-amino-4-ogy-3'-oxy-          4'-aminoarsenobenzol    reduziert.

   Das Präparat  löst sich leicht in Wasser. 52 g des salz  sauren Salzes werden in wässerigem Methyl  alkohol :gelöst,     dann    8     cmg    39     %ige    Natrium  bisulfitlösung     zugetropft    und hierauf 10 cm'  30      o        iger    Formaldehyd, zugefügt.

   Nach kur  zem     Nachrühren    gibt man nochmals 10,4     em3          Natriumbisulfitlösung,    sowie eine Lösung      von 13,9 g     Natriumsulfit    in 42 cm' Wasser  hinzu und fällt die neutralisierte Lösung in       Ethylalkohol.    Hierbei scheidet sich 3-(Di-         oxypropyl        -,oxyäthyl)        -amino-4-oxy-3'-oxy-4'        -          amino    -     arsenobenzol    -     formaldehydbisulfit-          natrium    der Formel

    als gelber Niederschlag aus.

   der abgesaugt  und mit Äther gewaschen wird. Die Verbin  dung löst sich leicht in Wasser.



  Process for the preparation of 3- (Diozypropyl-ogyäthyl) -amino-4-oay-3'-ogy-4'-amino-arsonobenzene-formaldehyde bisulfite sodium. From Swiss patent specification No. 157187 it is known that amino arsenobenzenes condense by reaction with alkylene oxides and sodium formaldehyde bisulphite to form oxyalkylaminoarsenobenzene - formaldehyde bisulphite compounds. to let.



  It has now been found that 3- (di-oxypropyl-oxyethyl) -amino-4-oxy-3'-oxy-4'-amino-arsenobenzene-formaldehyde bisulfite sodium can be prepared in such a way that 3- (dioxypropyl -oxyethyl)

  -amino-4-oxy-benzene-l-arsine acid is condensed with 3-O @ xy-4-aminobenzene- 1.-arsinic acid to form the corresponding asymmetric arsenobenzene derivative and the latter is reacted with sodium formaldehyde bisulfite.



  The new compound is a yellow powder which is easily soluble in water and insoluble in methyl alcohol, ethyl alcohol, ether and acetone. It should be used as a medicament, in particular as an antisyphilitic agent.



  <I> Example: </I> 35.1 g of 3- (dioxypropyl-oxyethyl) -amino-4-oxybenzene-l-arsinic acid, prepared according to German Patent No. 618447, Example 3, and 23.3 g of 3- Oxy-4-aminobenzene-l-arsinic acid, available according to German Patent No. 244166, are dissolved in hydrochloric acid and using hypophosphorous acid in the presence of potassium iodide to form hydrochloric acid 3- (dioxypropyl-oxyethyl) -amino-4-ogy -3'-oxy-4'-aminoarsenobenzene reduced.

   The preparation dissolves easily in water. 52 g of the acidic salt are dissolved in aqueous methyl alcohol, then 8 cmg of 39% sodium bisulfite solution are added dropwise and 10 cm of 30% formaldehyde is then added.

   After brief stirring, a further 10.4 cubic meters of sodium bisulfite solution and a solution of 13.9 g of sodium sulfite in 42 cm of water are added, and the neutralized solution is precipitated in ethyl alcohol. This separates 3- (dioxypropyl-, oxyethyl) -amino-4-oxy-3'-oxy-4 '- amino - arsenobenzene - formaldehyde bisulfite sodium of the formula
EMI0002.0011
    as a yellow precipitate.

   which is sucked off and washed with ether. The compound dissolves easily in water.
