Description
Verfahren zur Herstellung -von N-p-Aminobenzolsulfonylharnstoff. Im Hauptpatent ist ein Verfahren be schrieben zur Herstellung- des N-(p-Amino- benzolsulfonyl)-N'-methylharnstoffes, gemäss welchem man ein Methylcarbaminsäurehalo- genid mit Acetylsulfanilamid umsetzt und den erhaltenen N-(p-Acetylaminobenzolsulfo- nyl)-N'-methylharnstoff verseift.
Es wurde nun gefunden, dass man in ana loger Weise zum N-p-Aminobenzolsulfonyl- harnstoff gelangt, wenn. man p-Nitrobenzol- sulfonamid mit einem Carbaminsäurehaloge- nid umsetzt und in dem entstandenen N-p- Nitrobenzolsulfonylharnstoff die Nitrogruppe reduziert. Die neue Verbindung ist zur Ver wendung als Heilmittel und als Zwischen produkt bei der Herstellung von Heilmitteln bestimmt.
Man kann zum Beispiel Nitrobenzolsul- fonamid und Carbamidchlorid in einem Lö sungsmittel, z. B. Aceton oder Dioxan, auf zum Beispiel 50 bis 70 erhitzen. Das Haupt produkt ist in diesem Fall allerdings häufig der N,N'-Di-p-nitrosulfonylharnstoff, der of- fenbar durch Zersetzung des primär entstan denen N-Nitrosulfonylharnstoffes gebildet wurde. Zweckmässig ist es, säurebindende Stoffe zuzusetzen, wie z.
B. galiumcarbonat, Soda, Pyridin und andere, oder von den Sal zen des Nitrobenzolsulfonamids auszugehen. Hierbei erhält man den Monosulf onylharn- stoff ohne Beimengung des Disulfonharnstof- fes. Nach Reduktion der Nitrogruppe, z. B. durch Behandeln mit Zink und Salzsäure, er hält man den N-p-Aminobenzolsulfonylharn- stoff.
<I>Beispiel 1:</I> 20,2 g p-Nitrobenzolsulfonamid, 15,0 g wasserfreies galiumcarbonat und 100 cm' trockenes Aceton werden bei 60 unter Rüh ren mit einer Auflösung von 10,0 g Carb- amidsäurechlorid in 50 cm' trockenem Ace ton tropfenweise versetzt und anschliessend 20 Stunden zum Sieden erhitzt.
Nach Ab dämpfen des Acetons wird der Rückstand mit Wasser und Salzsäure bis zur kongo sauren Reaktion behandelt, und der Nieder- schlag wird nach dem Absaugen der Mutter lauge unter Rühren mit Wasser und Bicar- bonat behandelt. Aus der Bicarbonatlösung scheidet Salzsäure den in Lösung gegangenen p-Nitrobenzolsulfonylharnstoff als gelbes Pulver aus. Nach Kristallisation durch Auf lösen in warmem, verdünntem Ammoniak und Ansäuern mit Eisessig bildet die Verbin dung schöne Nadeln vom F. 190 bis 191 .
Durch Reduktion mit Zink und Salzsäure er hält man den N-p-Aminobenzolsulfonylharn- stoff vom F. 125 bis 127 in guter Ausbeute. <I>Beispiel 2:</I> 20,2 g p-Nitrobenzolsulfonamid, 9,0 g Carbamidsäurechlorid und 40 cm' Dioxan werden 24 Stunden auf 70 erhitzt.
Bei der Aufarbeitung wie nach Beispiel 1 erhält man neben viel symmetrischem Di-p-nitrobenzol- sulfonylharnstoff auch den p-Nitrobenzolsul- fonylharnstoff vom F. 190 bis 191 , den man, wie bei Beispiel 1 beschrieben, zur Amino- verbindung reduziert.
Process for the preparation of N-p-aminobenzenesulfonylurea. The main patent describes a process for producing the N- (p-aminobenzenesulfonyl) -N'-methylurea, according to which a methylcarbamic acid halide is reacted with acetylsulfanilamide and the N- (p-acetylaminobenzenesulfonyl) -N obtained '-methylurea saponified.
It has now been found that one arrives at N-p-aminobenzenesulfonyl urea in an analogous manner if. p-nitrobenzenesulfonamide is reacted with a carbamic acid halide and the nitro group is reduced in the resulting N-p-nitrobenzenesulfonylurea. The new compound is intended for use as a medicinal product and as an intermediate in the manufacture of medicinal products.
You can, for example, nitrobenzenesulfonamide and carbamide chloride in a solvent such. B. acetone or dioxane, for example 50 to 70 heat. In this case, however, the main product is often N, N'-di-p-nitrosulfonylurea, which was evidently formed by decomposition of the primarily N-nitrosulfonylurea that was formed. It is useful to add acid-binding substances, such as.
B. galium carbonate, soda, pyridine and others, or starting from the sal zen of nitrobenzene sulfonamide. The monosulfonylurea is obtained here without the addition of the disulfonicurea. After reduction of the nitro group, e.g. B. by treatment with zinc and hydrochloric acid, he holds the N-p-aminobenzenesulfonylurea.
<I> Example 1: </I> 20.2 g of p-nitrobenzenesulfonamide, 15.0 g of anhydrous galium carbonate and 100 cm 'of dry acetone are stirred at 60 cm with a resolution of 10.0 g of carbamic acid chloride in 50 cm 'Dry ace tone is added drop by drop and then heated to the boil for 20 hours.
After the acetone has been steamed off, the residue is treated with water and hydrochloric acid until the Congo acid reaction occurs, and the precipitate is treated with water and bicarbonate while stirring, after the mother liquor has been suctioned off. From the bicarbonate solution, hydrochloric acid separates the dissolved p-nitrobenzenesulfonylurea as a yellow powder. After crystallization by dissolving in warm, dilute ammonia and acidifying with glacial acetic acid, the compound forms beautiful needles with a temperature of 190 to 191.
Reduction with zinc and hydrochloric acid gives N-p-aminobenzenesulfonylurea with a melting point of 125 to 127 in good yield. Example 2: 20.2 g of p-nitrobenzenesulfonamide, 9.0 g of carbamic acid chloride and 40 cm of dioxane are heated to 70 for 24 hours.
Working up as in Example 1 gives, in addition to a large number of symmetrical di-p-nitrobenzenesulfonylurea, also p-nitrobenzenesulfonylurea with a melting point of 190 to 191, which, as described in Example 1, is reduced to the amino compound.
