Description
Verfahren zur Darstellung eines Aminobenzolsulfonsäureamidabkömmlings. In den schweizerischen Patentschriften Nr. 173540, 183916 und 183917 und andern sind Verfahren zur Darstellung von Azo- verbindungen beschrieben, die eine aus gezeichnete Wirkung bei der !Streptokokken- und Staphylokokkeninfektion der Warm blüter entfalten.
Bei all diesen nach den genannten Verfahren erhältlichen Azover- bindungen ist wesentlich, @dass der eine an die Azogruppe gebundene Rest ein cyclischer Rest ist, der entweder eine @Sulfonsäureamid- gruppe in der p-Stellung zur Azogruppe oder mehrere Sulfonsäureamidgruppen im Ring enthält.
Vorzugsweise erhält man .diese Ver bindungen mit Hilfe diazotierter Aminoben- zolsulfonsäureamide, die eine Sulfonsäure- amidgruppe in der p-.Stellung zur Amino- gruppe oder mehrere SulfonGäureamidgrup- pen im Ring gebunden enthalten.
Derartige Aminobenzolsulfonsäureamide besitzen an sich im Gegensatz zu anders substituierten Aminobenzolsulfonsäureamiden selbst eine bakterizide Wirkung. Die praktische Ver wendbarkeit ist jedoch dadurch beeinträch tigt, dass die für die praktische Verwendung hauptsächlich in Frage kommenden Salze mit starken :Säuren kongosaure Reaktion und demzufolge bei der Injektion starke Nekrosen geben.
Es wurde nun gefunden, dass man zu gut wirksamen Verbindungen unter Ver meidung der geschilderten Nachteile kommt, wenn man nach an sich üblichen Arbeits weisen Alkylsu@lfonsäure-, Alkylsulfinsäure- und Alkylcarbonsäureverbindungen solcher Aminobenzolsulfonsäureamide darstellt, die entweder eine Sulfonsäureamidgruppe in p-,Stellung zur Aminogruppe oder mehrere Sulfonsäureamidgruppen im Ring enthalten.
Der Benzolrest kann auch noch weitere Sub- stituenten tragen. Die Wasserstoffatome der Sulfonsäureamidgruppe(n) können dabei banz oder teilweise durch Alkyl-, Aralkyl-, Cycloalkylreste oder zwei Wasserstoffatome gleichzeitig durch einen Alkylenrest (unter Bildung eines gesättigten heterocyelischen Ringes) substituiert sein.
Die im Kern ge bundene Aminogruppe kann ausser durch die oben genannten Substituenten noch durch Alkyl, Aralkyl, Cycloalkyl oder Aryl substi tuiert sein. Die Alkylsulfonsäure-, Alkyl- sulfinsäure- und Alkylcarbonsäurereste kön nen zum Beispiel durch Hydroxylgruppeii substituiert sein.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Amino- benzolsulfonsäureamidabkömmlings, welches dadurch gekennzeichnet ist, dass man auf 2,5-Dimethyl-4-aminobenzolsulfonsäureamid Formaldeliydnatriumbisulfit einwirken lässt. Die Umsetzung erfolgt zweckmässig in Gegen wart eines Lösemittels, z. B. Glykol, und unter Erwärmen. Das Reaktionsprodukt lässt sich .durch eine Mischung von Alkohol und Äther abscheiden.
Man kann zum Beispiel Fornialdehydnatriumliisulfit verwenden, das bei Gegenwart des 2;5-Dimethyl-l-aminolx,n- zolsulfonsäureamids aus Formaldehyd und Natriumbisulfit hergestellt wurde. Das so erhaltene 2,5-Dimethyl-4-aminobenzolsulfon- sättreamid-N-inethansulfonsaure Natrium bil det farblose Kristalle. die in Wasser leicht löslich sind. Es soll therapeutische Anwen dung finden.
<I>Beispiel:</I> 20,0 g 2,5-Dimethyl-4-aminobenzolsulfon- säureamid vom Schmelzpunkt<B>190'</B> werden mit 17 g Formaldehydnatriumbisulfit und 50 cm' Äthylenglykol fünf lKinuten bis zur Lösung erhitzt und die erkaltete Lösung mit 400 cm' Alkohol und 400 cm' Äther versetzt. Die ausgeschiedene Formaldeliydnatrium- bisulfitverhindung wird abgesaugt, mit Äther gewaschen und getrocknet.
Process for the preparation of an aminobenzenesulfonic acid amide derivative. In the Swiss patents No. 173540, 183916 and 183917 and others, methods for the preparation of azo compounds are described, which develop an excellent effect in the streptococcal and staphylococcal infection of warm-blooded animals.
In all of these azo compounds obtainable by the processes mentioned, it is essential that the one radical bonded to the azo group is a cyclic radical which contains either a sulfonic acid amide group in the p-position to the azo group or several sulfonic acid amide groups in the ring.
These compounds are preferably obtained with the aid of diazotized aminobenzenesulfonic acid amides which contain a sulfonic acid amide group in the p-position to the amino group or several sulfonic acid amide groups bonded in the ring.
In contrast to differently substituted aminobenzenesulfonic acid amides, such aminobenzenesulfonic acid amides themselves have a bactericidal effect. However, the practical usability is impaired by the fact that the salts which are mainly suitable for practical use with strong acids: Congo-acidic reactions and consequently give strong necroses on injection.
It has now been found that compounds that are effective while avoiding the disadvantages outlined are obtained if, according to conventional work, alkylsulfinic acid, alkylsulfinic acid and alkylcarboxylic acid compounds of those aminobenzenesulfonic acid amides which either have a sulfonic acid amide group in p-, position to Amino group or more sulfonic acid amide groups contained in the ring.
The benzene radical can also carry further substituents. The hydrogen atoms of the sulfonic acid amide group (s) can be completely or partially substituted by alkyl, aralkyl, cycloalkyl radicals or two hydrogen atoms simultaneously by an alkylene radical (with formation of a saturated heterocyclic ring).
The amino group bonded in the core can be substituted by alkyl, aralkyl, cycloalkyl or aryl in addition to the abovementioned substituents. The alkylsulfonic acid, alkylsulfinic acid and alkylcarboxylic acid radicals can be substituted, for example, by hydroxyl groups.
The subject matter of the present patent is a process for the production of an aminobenzenesulfonic acid amide derivative, which is characterized in that formaldelium sodium bisulfite is allowed to act on 2,5-dimethyl-4-aminobenzenesulfonic acid amide. The implementation is expediently carried out in the presence of a solvent, e.g. B. Glycol, and with heating. The reaction product can be separated by a mixture of alcohol and ether.
For example, sodium formaldehyde sulphite can be used, which was prepared from formaldehyde and sodium bisulphite in the presence of 2; 5-dimethyl-1-aminolx, n-zolsulphonic acid amide. The 2,5-dimethyl-4-aminobenzenesulfonate sättreamid-N-inethanesulfonsaure thus obtained forms colorless crystals. which are easily soluble in water. It should find therapeutic use.
<I> Example: </I> 20.0 g of 2,5-dimethyl-4-aminobenzenesulphonic acid amide with a melting point of <B> 190 '</B> are combined with 17 g of formaldehyde sodium bisulphite and 50 cm' of ethylene glycol to dissolve in five minutes heated and the cooled solution is mixed with 400 cm 'of alcohol and 400 cm' of ether. The precipitated formaldelium bisulfite compound is filtered off with suction, washed with ether and dried.
