Description

  

  Verfahren zur Herstellung von     1-Phenyl-2,3-dimethyl-4-(methyl-cyclohegenyl)-          amino-ö-pyrazolon.       Gegenstand der Erfindung ist ein Ver  fahren zur Herstellung von     1-Pheny1-2,3-di-          methyl-4-(m        ethyl-cycloh        exenyl)-ani    i     rio    -5-     pyr-          azolon,    das dadurch gekennzeichnet ist, dass  man     1-Phenyl-2,3-diinethyl-4-methylamin-5-          pyrazolon    mit     1-Bromeyclohexen-2,3    umsetzt.  



  Die neue Verbindung ist in Wasser  schwer, in den meisten organischen Lösungs  mitteln leicht löslich. Sie schmilzt bei 84  bis 86   und soll als Arzneimittel verwendet  werden.  



  <I>Beispiel:</I>  217 Gewichtsteile     1-Pheriyl-2,3-dimethyl-          4-methylamino-5-pyrazolon    werden in Benzol  gelöst und mit 80,5 Gewichtsteilen     1-Brom-          cyclohexen-2,3    auf dem Dampfbad gekocht.  Das so entstandene     1-Phenyl-2,3-diniethyl-          4-(methyl-cyclohexenyl)-amino-5-pyrazolori       schmilzt nach dem     ITmkristallisieren    aus ver  dünntem Alkohol bei 84-86  . Es <  ist in  den meisten organischen Lösungsmitteln  leicht, in Wasser schwer löslich.



  Process for the preparation of 1-phenyl-2,3-dimethyl-4- (methyl-cyclohegenyl) -amino-ö-pyrazolone. The invention relates to a process for the preparation of 1-Pheny1-2,3-dimethyl-4- (m ethyl-cyclohexenyl) -ani i rio -5-pyr-azolone, which is characterized in that 1 -Phenyl-2,3-diinethyl-4-methylamine-5-pyrazolone is reacted with 1-bromyclohexene-2,3.



  The new compound is difficult in water and easily soluble in most organic solvents. It melts at 84 to 86 and is said to be used as a medicine.



  <I> Example: </I> 217 parts by weight of 1-pheriyl-2,3-dimethyl-4-methylamino-5-pyrazolone are dissolved in benzene and mixed with 80.5 parts by weight of 1-bromocyclohexene-2,3 on the steam bath cooked. The 1-phenyl-2,3-diniethyl-4- (methyl-cyclohexenyl) -amino-5-pyrazolori formed in this way melts after IT crystallization from dilute alcohol at 84-86. It <is easily soluble in most organic solvents and sparingly soluble in water.
