Die Reduktion der von Michaelis (B. 27 [1894], S. 265; A. 320 [1902], S. 294) dargestellten Nitrophenylarsinsäure, die den Substitutionsgesetzen zufolge die Nitrogruppe zum Arsensäurerest in Metastellung enthalten muß, zur entsprechenden m - Aminophenylarsinsäure ist bisher nicht gelungen (s. A. 320 [1902], S. 277). Nur ein Aminophenylarsensulfid, N H2CeHiAs S, wurde von Michaelis (Ber. 27 [1894], S. 271) dargestellt.The reduction of the nitrophenylarsinic acid presented by Michaelis (B. 27 [1894], p. 265; A. 320 [1902], p. 294), which according to the laws of substitution must contain the nitro group meta to the arsenic acid residue, to the corresponding m-aminophenylarsinic acid not yet successful (see A. 320 [1902], p. 277). Only one aminophenyl arsenic sulfide, NH 2 C e H i As S, was presented by Michaelis (Ber. 27 [1894], p. 271).
Es wurde nun gefunden, daß die m-Aminophenylarsinsäure (Metarsanilsäure) dargestellt werden kann:It has now been found that m-aminophenylarsinic acid (Metarsanilic acid) can be represented:
1. durch Einwirkung von Natriumamalgam auf jene bekannte Nitrophenylarsinsäure in alkoholischer Lösung,1. by the action of sodium amalgam on that known nitrophenylarsinic acid in alcoholic solution,
2. durch Entschwefelung der bei der Einwirkung von Schwefelammonium auf Nitrophenylarsinsäure entstehenden Aminophenylarsensulfide mit Metalloxyden in alkalischer Lösung.2. by desulfurization of the action of ammonium sulphide on nitrophenylarsinic acid resulting aminophenyl arsenic sulfides with metal oxides in alkaline Solution.
Da bei der Darstellung dieser Sulfide ein Gemenge verschiedener Oxydationsstufen:Since in the representation of these sulphides a mixture of different oxidation stages:
v.v.
III.III.
und NH2C6HiAsS and NH 2 C 6 HiAsS
erhalten wird, so empfiehlt es sich, zur Entschwefelung Kupferoxyd anzuwenden, wobei die Derivate des dreiwertigen Arsens zugleich wieder oxydiert werden.is obtained, it is advisable to use copper oxide for desulfurization, with the derivatives of trivalent arsenic are oxidized again at the same time.
I. Reduktion der Nitrophenylarsinsäure mit Natriumamalgam.I. Reduction of nitrophenylarsinic acid with sodium amalgam.
99 g Nitrophenylarsinsäure werden in 21 Methylalkohol gelöst und mit 2,8 kg 4prozentigem Natriumamalgam so lange bei 500 digeriert, bis die Wasserstoffentwicklung aufgehört hat. Hierauf wird vom Quecksilber abfiltriert, der Methylalkohol abdestilliert, der Rückstand mit 8 bis 9 1 Wasser aufgenommen und die Lösung mit Essigsäure neutralisiert. Auf Zusatz von überschüssigem Zinkacetat fällt das Zinksalz der m - Aminophenylarsinsäure aus, das mit Natriumcarbonat zerlegt wird. Das Filtrat von Zinkcarbonat, mit Salzsäure neutralisiert, scheidet auf Zusatz von Eisessig die Metarsanilsäure als weißes Pulver ab.99 g are dissolved in 21 Nitrophenylarsinsäure methyl alcohol and digested with 2.8 kg 4prozentigem sodium amalgam as long as at 50 0, stopped until the evolution of hydrogen. The mercury is then filtered off, the methyl alcohol is distilled off, the residue is taken up in 8 to 9 liters of water and the solution is neutralized with acetic acid. When excess zinc acetate is added, the zinc salt of m-aminophenylarsinic acid precipitates and is broken down with sodium carbonate. The filtrate of zinc carbonate, neutralized with hydrochloric acid, separates the metarsanilic acid as a white powder when glacial acetic acid is added.
II. Reduktion mit Schwefelammonium. _0 II. Reduction with sulfur ammonium. _ 0
200 g Nitrophenylarsinsäure werden in 1,4 1 25 prozentigem Ammoniaks gelöst, die Lösung mit Schwefelwasserstoff gesättigt, darauf 12 Stunden auf dem Wasserbade erwärmt und die Behandlung mit Schwefelwasserstoff und das Erwärmen nochmals wiederholt. Hierauf wird zur Trockne gedampft,- der Rückstand mehrfach mit stark verdünnter Salzsäure ausgezogen, die Auszüge auf 10 1 verdünnt und nach Zufügung von 1,41 zehnfach normaler200 g of nitrophenylarsinic acid are dissolved in 1.4 liters of 25 percent ammonia, the solution saturated with hydrogen sulfide, then warmed on the water bath for 12 hours and the treatment with hydrogen sulfide and the heating are repeated again. On that is evaporated to dryness, - the residue is extracted several times with very dilute hydrochloric acid, the extracts diluted to 10 1 and ten times more normal after the addition of 1.41
Natronlauge zum Sieden erhitzt. Man läßt nun so lange normale Kupfersulfatlösung zutropfen, bis eine filtrierte Probe beim Kochen mit Bleiacetat keinen Niederschlag von Schwefelblei mehr gibt. Man filtriert dann vom Schwefelkupfer ab, neutralisiert mit Essigsäure und gewinnt die freie Säure über das Zinksalz, wie im Beispiel I beschrieben.Sodium hydroxide solution heated to the boil. Normal copper sulphate solution is now allowed to drip in until until a filtered sample boiled with lead acetate no precipitate of lead sulfur more there. The copper sulphide is then filtered off and neutralized with acetic acid and wins the free acid via the zinc salt, as described in Example I.
Die m - Aminophenylarsinsäure (Metarsanilsäure) schmilzt bei 212 bis 2140, wodurch sie sich von der bei 2300 noch nicht schmelzenden ρ - Aminophenylarsinsäure unterscheidet. Sie kristallisiert aus Wasser in farblosen Prismen, ist schwer löslich in heißem Wasser, mäßig löslich in Methylalkohol, schwer löslich in Äthylalkohol, Eisessig und Äther. Von Alkalien und Mineralsäuren wird sie gelöst. Sie läßt sich leicht diazotieren und liefert mit Magnesiamischung erhitzt einen weißen Niederschlag.The m - Aminophenylarsinsäure (Metarsanilsäure) melts at 212-214 0, which extend from the not yet melting at 230 0 ρ - differs Aminophenylarsinsäure. It crystallizes from water in colorless prisms, is sparingly soluble in hot water, moderately soluble in methyl alcohol, sparingly soluble in ethyl alcohol, glacial acetic acid and ether. It is dissolved by alkalis and mineral acids. It can be easily diazotized and, when heated with a magnesia mixture, gives a white precipitate.
Die neue Verbindung dient therapeutischen Zwecken.The new compound is used for therapeutic purposes.
