Verfahren <SEP> zur <SEP> Darstellung <SEP> von <SEP> 3-(Diogypropyl-ogäthyl)-amino-4-ogy-3'-methylamino 4'-ogyarsenobenzol-3'-N-formaldehydnatrinmsulfogylat. Das Hauptpatent betrifft ein Verfahren zur Herstellung von Z-Oxy-4-(bis-,dioxypro- pyl) - amino - 4'- oxyarsenobenzol - 3' -methyl- aminoforma1dehydnatrium3u]foxylat, welches dadurch gekennzeichnet ist, dass mit 1 Mol '3-Oxy-4-amiuoben#zol-1-arsinsäure,
1 Mol 3- Methylamino-4-oxybenzol-l-arsinsäure, 2 Mol Glycid, ein Reduktionsmittel und Formal dehydnatriumsulfoxylat aufeinander einwir ken lässt.
Es wurde nun gefunden, dass man zu einer . Verbindung von gleich wertvollen pharmakologischen Eigenschaften gelangen kann, wenn man 1 Mol 3-Amino-4-oxybenzol- 1-arsinsäure, 1 Mol 3-.Methylamino-4-oxyben- zol-l-arsin3äure, 1 Mol Äthylenoxyd, 1 Mol Glycid,
ein Reduktionsmittel und Formal- dehydnatriumsulfoxylat aufeinander einwir ken lässt. Erfindungsgemässe kann man z. B. 3-(Dioxypropyl -oxä@thyl) - amino -4-oxybenzol- 1-arsinsäure, 3-Methylamino-4-oxybenzol-l- arsinsäure durch gemeinsame Reduktion in das entsprechende 3-(Dioxypropyl-oxäthyl)
- amino -4- oxy-3'-methylamino -4 '- oxyarseno- benzol überführen und dieses mit Formal- d-ehydnatriumsulfoxylat zu 3-(Dioxypropyl- oxäthyl) -amino-4-oxy-,3'-methylam#ino-4'-oxy- arsenobenzol- 3'-N -f ormaId,ehydnatriumsulfo- xylat umsetzen.
Zu der ,gleichen Verbindung kann man auch gelangen, wenn man aus 3-Amino-4- oxybe7azol-l=arsinsäure und 3-Methylamino- 4-oxybenzol-1-arsinsäure durch gemeinschaft- liche Reduktion das entsprechende Arseno- benzol bildet,
dieses mit FormaIdehyd- natriumsulfoxylat zu dem entsprechenden Monosulfogylat umsetzt und auf die wässe rige Lösung dieses Monosulfoxylates unter Kühlung ein Molekül Äthylenoxyd und so dann in .der Wärme ein Molekül Glycid ein- wirken lässt.
Die so erhaltene neue Verbindung bildet ein in Wasser leicht lösliches, in Äther und Äthylalkohol unlösliches gelbes Pulver. Sie soll als Heilmittel verwendet werden.
Beispiel: 35,1 g 3-(Dioxypropyl-oxäthyl)-amino-4- oxybenzol-1-arsinsäure und 24,7 g 3-Methyl- amino-4-oxybenzol-l-arsinsäure werden in 600 cm3 10 %zger Salzsäure gelöst, mit Tier kohle entfärbt und unter Rühren 80 cm' 50%ige unterphosphorige Säure, sowie eine Lösung von -30, g Kal.iumjo.did in 30 cm' Wasser zugesetzt. Hierbei steigt die Tempe ratur auf etwa 40' C.
Nach beendigter Um setzung werden: 6,0:0 cm' eiskalte konzen trierte Salzsäure zugefügt; die klare Flüssig keit wird in 6,5 Liter Äthylalkohol einge- rührt.
Hierbei scheidet sich ein orangefarbe ner Niederschlag von salzsaurem 3-(Dioxy- propyl - oxäthyl) - amino- 4 - oxy - 3'- methyl- amino-4'-oxyarsenobenzol ab, der abgesaugt und mit Äther gewaschen wird.
40 g dieses salzsauren Salzes werden in wässrigem Methylalkohol -gelöst und mit einer Lösung von 28 g Formaldehydnatriumsulf- oxylat in 56 em3 Wasser 20 Minuten auf etwa 30 C erwärmt, ,dabei scheidet sich ein dunkelgelber Niederschlag aus, der auf Zu satz von Natriumcarbonat wieder in Lösung geht.
Wird diese Flüssigkeit in ein Gemisch von Äthylalkohol und Äther eingerührt, so fällt ein dunkelgelber Niederschlag von 3 - (Dioxypropyl - oxäthyl) - amino-4-oxy-3'- methylamino-4'-oxyarsenobenzol-3'-N-f ormal- d:ehydnatriums#ulfoxylat

aus, :der abgenutscht und mit Äther gewa- sehen wird. Das Präparat enthält l9,5 Arsen und ist in Wasser löslich.
Dieselbe Verbindung wird auch erhalten, indem man molekulare Mengen von 3- Amino- 4-oxybenzol-l-arsinsäure und 3-Methylamino- 4-axybenzol-l-arsinsäure in üblicher 'Weise mittels unterphosphoriger Säure und Jodkali zur asymmetrischen Arsenoverbindung redu ziert und mit Formaldehydnatriumsulfoxylat in das entsprechende
Sulfoxylat überführt. Lässt man auf die wässerige Lösung des Sulfoxylates unter Kühlung ein Molekül Äthylenogyd und dann in der Wärme ein Molekül Glyci@d einwirken, so entsteht das 3 - (Dioxypropyl - oxäthyl) - amino-4-oxy-3'- methylamino - 4'- oxyarsenobenzolsulfoxylat,
das aus :der wäss:rigen Lösung durch Äthyl- alkohol und Äther gefällt wird. Beide Ver bindungen zeigen dieselben chemischen Ei- genschaften und die gleiche pharmakologi sche Wirksamkeit, so dass hiermit ihre Iden tität erwiesen ist.
Die eingangs, :des Beispiels erwähnte 3- (Dioxypropyl -oxäthyl)-amino -4- oxybenzol-l- arsinsäure wird erfindungsgemäss durch Ein wirkung von 1 Mol Äthylenoxyd und 1 Mol Glycid auf :3-Amino-4-oxybenzol-l-arsinsäure hergestellt. Die fast farblose Säure löst sich spielend in Wasser und Methylalkohol und enthält 3,8 % N.

Method <SEP> for <SEP> preparation <SEP> of <SEP> 3- (diogypropyl-ogäthyl) -amino-4-ogy-3'-methylamino 4'-ogyarsenobenzene-3'-N-formaldehyde sodium sulfogylate. The main patent relates to a process for the preparation of Z-oxy-4- (bis-, dioxypropyl) -amino-4'-oxyarsenobenzene-3'-methyl-aminoforma1dehydnatrium3u] foxylate, which is characterized in that with 1 mol '3 -Oxy-4-amiuoben # zol-1-arsic acid,
1 mole of 3-methylamino-4-oxybenzene-l-arsinic acid, 2 moles of glycide, a reducing agent and formaldehyde sodium sulfoxylate can interact.
It has now been found that one can become a. Compound of equally valuable pharmacological properties can be achieved if 1 mol of 3-amino-4-oxybenzene-1-arsinic acid, 1 mol of 3-methylamino-4-oxybenzene-1-arsinic acid, 1 mol of ethylene oxide, 1 mol of glycide,
a reducing agent and sodium formaldehyde sulfoxylate interact. According to the invention you can, for. B. 3- (Dioxypropyl -oxä @ thyl) - amino -4-oxybenzene- 1-arsinic acid, 3-methylamino-4-oxybenzene-l-arsic acid by joint reduction into the corresponding 3- (dioxypropyl-oxäthyl)
- Amino -4- oxy-3'-methylamino -4 '- oxyarsenobenzene and this with formaldehyde sodium sulfoxylate to 3- (dioxypropyl-oxäthyl) -amino-4-oxy-, 3'-methylam # ino- 4'-oxy-arsenobenzene-3'-N -form, ehydsodium sulfoxylate.
The same compound can also be obtained if the corresponding arsenobenzene is formed from 3-amino-4-oxybe7azol-1-arsic acid and 3-methylamino-4-oxybenzene-1-arsic acid by joint reduction,
this is reacted with sodium formaldehyde sulfoxylate to form the corresponding monosulfogylate and a molecule of ethylene oxide and then a molecule of glycide act on the aqueous solution of this monosulfoxylate while cooling.
The new compound thus obtained forms a yellow powder which is easily soluble in water and insoluble in ether and ethyl alcohol. It is said to be used as a remedy.
Example: 35.1 g of 3- (dioxypropyl-oxethyl) -amino-4-oxybenzene-1-arsic acid and 24.7 g of 3-methyl-amino-4-oxybenzene-1-arsic acid are dissolved in 600 cm3 of 10% hydrochloric acid , decolourised with animal charcoal and 80 cm 'of 50% hypophosphorous acid and a solution of -30 g of potassium jo.did in 30 cm of water were added while stirring. The temperature rises to around 40 ° C.
After the conversion is complete: 6.0: 0 cm 'ice-cold concentrated hydrochloric acid is added; the clear liquid is stirred into 6.5 liters of ethyl alcohol.
An orange precipitate of hydrochloric acid 3- (dioxypropyl-oxethyl) -amino-4-oxy-3'-methyl-amino-4'-oxyarsenobenzene separates out, which is filtered off with suction and washed with ether.
40 g of this hydrochloric acid salt are dissolved in aqueous methyl alcohol and heated to about 30 ° C. for 20 minutes with a solution of 28 g of sodium formaldehyde sulfoxylate in 56 em3 of water, a dark yellow precipitate separating out, which is reassigned to the addition of sodium carbonate Solution works.
If this liquid is stirred into a mixture of ethyl alcohol and ether, a dark yellow precipitate of 3 - (dioxypropyl-oxethyl) -amino-4-oxy-3'-methylamino-4'-oxyarsenobenzene-3'-Nf ormal- d: ehydsodium sulfoxylate

off: which is sucked off and washed with ether. The preparation contains 19.5 arsenic and is soluble in water.
The same compound is also obtained by reducing molecular amounts of 3-amino-4-oxybenzene-1-arsinic acid and 3-methylamino-4-axybenzene-l-arsinic acid in the usual way by means of hypophosphorous acid and potassium iodide to the asymmetric arsenic compound and with Formaldehyde sodium sulfoxylate into the corresponding
Sulphoxylate transferred. If a molecule of ethylenogide is allowed to act on the aqueous solution of the sulfoxylate with cooling and then a molecule of Glyci @ d in the heat, the 3 - (dioxypropyl - oxäthyl) - amino-4-oxy-3'-methylamino - 4'- oxyarsenobenzene sulfoxylate,
which is precipitated from: the aqueous solution by means of ethyl alcohol and ether. Both compounds show the same chemical properties and the same pharmacological effectiveness, so that their identity is hereby proven.
The 3- (dioxypropyl-oxethyl) -amino -4-oxybenzene-l-arsic acid mentioned at the beginning: is according to the invention by action of 1 mole of ethylene oxide and 1 mole of glycide on: 3-amino-4-oxybenzene-l-arsic acid manufactured. The almost colorless acid dissolves easily in water and methyl alcohol and contains 3.8% N.
