Description

  

  Verfahren zur Darstellung von     1-Perhydrocarbazyläthyl-5-methylpyrazolin.       Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Darstellung von     1-Per-          hydrocarbazyläthyl-5-methylpyrazolin,    wel  ches darin besteht, dass man     N-Chloräthyl-          perhydrocarbazol    mit     5-Methylpyrazolin    um  setzt.  



  Die neue Verbindung ist als Heilmittel  verwendbar und stellt ein gelbliches, unter  4 mm Druck bei l73-180   siedendes 01  dar; sie bildet ein farbloses, bei 187   schmel  zendes     Monobromhydrat.     



  <I>Beispiel:</I>  18 Teile     N-_Chloräthylperhydrocarbazol          (vergl.    Beispiel des Hauptpatentes) und 13  Teile     5-Methylpyrazolin    werden 1 Stunde  lang auf dem Dampfbad erwärmt. Man ver  setzt nach dem Erkalten mit Wasser und  Natronlauge, nimmt das so erhaltene     1-Per-          hydrocarbazyläthyl-5-methylpyrazolin     
EMI0001.0013     
    in Äther auf und reinigt es durch Vakuum  destillation. Das Produkt ist ein gelbliches  01, dessen Siedepunkt bei 4 mm Druck bei  173-180   liegt; es bildet ein farbloses       Monobromhydrat,    das bei 187<B>0 0</B> schmilzt.



  Process for the preparation of 1-perhydrocarbazylethyl-5-methylpyrazoline. The present invention relates to a process for the preparation of 1-per-hydrocarbazylethyl-5-methylpyrazoline, which consists in that N-chloroethyl perhydrocarbazole is reacted with 5-methylpyrazoline.



  The new compound can be used as a remedy and represents a yellowish oil boiling under 4 mm pressure at 173-180; it forms a colorless monobromohydrate that melts at 187.



  <I> Example: </I> 18 parts of N-_Chloräthylperhydrocarbazol (see. Example of the main patent) and 13 parts of 5-methylpyrazoline are heated for 1 hour on the steam bath. After cooling, one sets ver with water and sodium hydroxide solution, takes the 1-perhydrocarbazylethyl-5-methylpyrazoline thus obtained
EMI0001.0013
    in ether and purifies it by vacuum distillation. The product is a yellowish oil, the boiling point of which at 4 mm pressure is 173-180; it forms a colorless monobromohydrate that melts at 187 <B> 0 0 </B>.
