  Verfahren zur Herstellung des neuen   2, 4-Disulfamyl-5-trifluormethyl-anilins   
Gegenstand der vorliegenden Erfindung ist   ein Verfahren zur Herstellung des neuen 2, 4- Disulfarnyl-5-trifluormethyl-anilins der Formel :    
 EMI1.1 
 
Diese Verbindung zeigt gegenüber vergleichbaren bekannten Verbindungen eine gute diuretische Wirksamkeit und kann vorteilhaft als Heilmittel Verwendung finden, z. B. in Form von pharmazeutischen Präparaten, welche diese Verbindung zusammen mit pharmazeutischen anorganischen oder organischen, festen oder flüssigen Trägerstoffen, die für enterale, z. B. orale, oder parenterale Verabreichung geeignet sind, enthalten. Sie ist ferner ein wertvolles Zwischenprodukt zur Herstellung von hochwirksamen Diuretika und/oder Natriuretika, wie z.

   B. des   6- Triflourmethyl-7-sulfamyl-I, 2, 4-benzo-     thiadiazin-l. l-dioxyds.    



   Die neue Verbindung lässt sich erhalten, wenn man   5-Trifluormethyl-anilin-2, 4-disulfonyl-   chlorid mit Ammoniak, vorzugsweise mit einer wässerigen Ammoniaklösung, umsetzt. Dabei erhitzt man die Reaktionslösung vorzugsweise auf   1000   C. 



   Das als Ausgangsmaterial verwendete 5-Tri-   fluormethyl-anilin-2,4-disulfonylchloridkann z.B.    durch Erhitzen von 3- Trifluormethyl-anilin mit einem Überschuss Chlorsulfonsäure, gegebenenfalls in Gegenwart eines schwefelsäurebindenden oder Halogenierungsmittels, wie Kochsalz, Thionylchlorid, Sulfonylchlorid, Phosphortrichlorid, Phosphorpentachlorid, Tetrachlorkohlenstoff, Hexachloräthan oder Tetrachloräthylen, erhalten werden.

  Process for the preparation of the new 2,4-disulfamyl-5-trifluoromethyl-aniline
The present invention relates to a process for the preparation of the new 2,4-disulfarnyl-5-trifluoromethyl-aniline of the formula:
 EMI1.1
 
This compound shows good diuretic activity compared to comparable known compounds and can advantageously be used as a medicinal product, e.g. B. in the form of pharmaceutical preparations, which this compound together with pharmaceutical inorganic or organic, solid or liquid carriers, which for enteral, z. B. oral, or parenteral administration are suitable included. It is also a valuable intermediate for the production of highly effective diuretics and / or natriuretics, such as.

   B. 6-trifluoromethyl-7-sulfamyl-1,2,4-benzothiadiazine-1,2. l-dioxyds.



   The new compound can be obtained if 5-trifluoromethyl-aniline-2,4-disulfonyl chloride is reacted with ammonia, preferably with an aqueous ammonia solution. The reaction solution is preferably heated to 1000 C.



   The 5-trifluoromethyl-aniline-2,4-disulfonyl chloride used as starting material can e.g. by heating 3-trifluoromethyl-aniline with an excess of chlorosulfonic acid, optionally in the presence of a sulfuric acid-binding or halogenating agent such as common salt, thionyl chloride, sulfonyl chloride, phosphorus trichloride, phosphorus pentachloride, carbon tetrachloride, hexachloroethane or tetrachlorethylene.
