Die Erfindung betrifft die Herstellung von 3-Sulfanilamido-4-methyl-isoxazol
der Formel I
sowie von dessen Salzen.

und das erhaltene 3-Sulfanilamido-4-methyl-isoxazol erwi.;;ischtcnfalls in an sich bekannter Weise mit
;mer basisch reagierenden Verbindung in ein Salz überführt.
Die Umsetzung des 3-Amino-4-methyl-isoxazols mit dem Benzolsulfohalogenid kann z. B. in Pyridin
bei Temperaturen im Bereich von etwa 0 bis 5O0C vorgenommen werden.
Die Salzbildung kann beispielsweise mit anorganischen
oder stärkeren organischen Basen, wie Alkali- oder Erdalkalihydroxyden oder -carbonaten.
bzw. mit Aminen, wie Äthanolamin oder Diäthanoiamin, vorgenommen werden.
Das erfindungsgemäß erhältliche 3-Sulfanilamido-4-methyl-isoxazol
der Formel I zeichnet sich durch hohe chemotherapeutische Aktivität gegen die verschiedensten
Infektionserreger aus, wie Escheriechia coil, Pneumokokken, Streptokokken, Staphylokokken
und Salmonellen. So ist das 3-Sulfanilamido-4-methyl-isoxazol
dem z. B. aus der deutschen Auslegeschrift 1 059 459 bekannten, isomeren 3-Sulfanilamido-5-methyJ-isoxazol
chemotherapeutisch insofern überlegen, als es. bei vergleichbarer Toxizität.
gegen Salmonella typhi murium dreimal aktiver ist.

Beanspruchte Priorität:
Schweiz vom 6. August 1963 (9706)
9,8 g (0,1 Mol) 3-Amino-4-methyl-isoxazol werden in 80 ml absolutem Pyridin gelöst. Zur Lösung gibt
man 25,7 g p-Acetamino-benzolsulfochlorid. Man
läßt dabei die Temperatur nicht über 450C steigen.
Nach einer Stunde wird das Gemisch in 400 ml Eiswasser gegossen. Man erhält so das 3-(N-Acetylsulfanilamido)-4-methyl-isoxazol
vom Schmelzpunkt 235° C. Dieses wird mit 10%iger Natronlauge auf dem siedenden Wasserbad verseift. Aus der filtrierten
Lösung fällt das 3-Sulfanilamido-4-methyl-isoxazol reinweiß und kristallin aus. Ausbeute 15,7 g;
Schmelzpunkt 182 bis 183 C (aus Methanol).
