Description

  

  Verfahren zur Herstellung von     1-eyclohegyl-2,3-dimethyl-4-methylamino-5-pyrazolon-          4-methansulfonsaurem    Chinin.    Im Hauptpatent ist ein Verfahren zur  Herstellung von     1-pherryl-2,3-dimetbyl-4-me-          thylamirro-5-pyrazolon-4-methansulforrsaurem     Chinin beschrieben, welches dadurch gekenn  zeichnet ist, dass man 1-Phenyl-2,3-dimethyl       4-methylamino-5-pyrazolon-4-methansulforr-          säure    mit     Chininbase    zur Umsetzung bringt.  



  Es wurde gefunden, dass man     1-cyclo-          h        exyl    - 2,3 -     dimethyl    - 4-     methylamino    - 5 -     pyr-          azolon-4-methansulforrsaures    Chinin erhält,  wenn man     1-Cyclohexyl-2,3-dimethyl-4-me-          thylamino    - 5 -     pyrazolon    - 4-     methansulfonsäure     mit     Chininbase    zur Umsetzung bringt. Dabei  kann man z.

   B.     1-Cyclohexyl-2,3-dimethyl-4-          methylamino-5-pyrazolon.4-methansulfonsäur-e     verwenden, die durch Einwirkenlassen von  Formaldehyd und schweflige Säure auf     1-          Cyclohexyl-2,        3-dimethyl-4-m        ethyl        ainin        o.5-pyr-          azolon    in Gegenwart der     Chininbase    erhalten  wurde.    Die neue Verbindung bildet farblose, in  Wasser leicht, in     Methyl-    und Äthylalkohol  schwerer, und in Aceton und Äther fast un  lösliche Kristalle.

   Sie stellt ein wertvolles  Arzneimittel dar, welches die Wirkung der  einzelnen Ausgangsstoffe     übertrifft.    Sie kann  gegebenenfalls mit einzelnen     Arzneistoffen     gemischt werden und soll in der Therapie  Verwendung finden.    <I>Beispiel:</I>    7,4 g     Chininbase    und 6,6 g     1-Cyclohexyl-          2,3    -     dimetbyl    - 4 -     methylamino-    5     -pyrazolon-4-          methansulfonsäure    (dargestellt nach dem  Schweizer Patent Nr. 184875) werden in  40 cm' Aceton gelöst und mit Äther bis zur  beginnenden Trübung versetzt.

   Beim Ab  kühlen kristallisiert das gebildete     Chininsalz     aus, das mit Äther nachgewaschen wird.  Schmelzpunkt<B>151-1530</B> C. Das Salz ist in  Wasser löslich.



  Process for the preparation of 1-eyclohegyl-2,3-dimethyl-4-methylamino-5-pyrazolone-4-methanesulfonic acid quinine. The main patent describes a process for the preparation of 1-pherryl-2,3-dimetbyl-4-methylamirro-5-pyrazolone-4-methanesulforrsaurem quinine, which is characterized in that 1-phenyl-2,3- dimethyl 4-methylamino-5-pyrazolone-4-methanesulforric acid with quinine base for implementation.



  It has been found that 1-cyclohexyl-2,3-dimethyl-4-methylamino-5-pyrazolone-4-methanesulfuric quinine is obtained when 1-cyclohexyl-2,3-dimethyl-4-me is obtained - brings thylamino - 5 - pyrazolon - 4 - methanesulfonic acid with quinine base to implement. You can z.

   B. 1-Cyclohexyl-2,3-dimethyl-4-methylamino-5-pyrazolon.4-methanesulfonic acid-e use which by the action of formaldehyde and sulphurous acid on 1- cyclohexyl-2,3-dimethyl-4-m ethyl ainine o.5-pyrazolone was obtained in the presence of the quinine base. The new compound forms colorless crystals, easily soluble in water, more difficult in methyl and ethyl alcohol, and almost insoluble in acetone and ether.

   It is a valuable medicine that exceeds the effects of the individual raw materials. If necessary, it can be mixed with individual drugs and should be used in therapy. <I> Example: </I> 7.4 g quinine base and 6.6 g 1-cyclohexyl- 2,3 - dimetbyl - 4 - methylamino- 5-pyrazolone-4-methanesulphonic acid (shown according to Swiss patent no. 184875) are dissolved in 40 cm 'acetone and mixed with ether until the onset of turbidity.

   When cooling down, the quinine salt formed crystallizes out, which is washed with ether. Melting point <B> 151-1530 </B> C. The salt is soluble in water.
