Description

  

  Verfahren zur Herstellung einer     heteroeyklisehen    Verbindung.    Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer     heterocyk-          lischen    Verbindung, dadurch gekennzeichnet,  dass man ein Gemisch von     Tetrahydrocarbo-          lin    der Formel  
EMI0001.0006     
    einer wasserstoffaufnehmenden Substanz und  einem     Hydrierungskatalysator    erhitzt.    - Das so erhaltene     Carbolin    ist bekannt.       1s    schmilzt in reinem Zustande bei 2100 C       (vergl.        Chem.    Zentralblatt 1924, 1. S. 2518).

    Es soll als Zwischenprodukt zur Herstellung  von Farbstoffen und pharmazeutischen Pro  dukten Verwendung finden.    <I>Beispiel:</I>  30 Teile     Tetrahydro-carbolin    der Formel  
EMI0001.0013     
    werden mit 60 Teilen Phenol und 1 Teil  eines     Hydrierungskatalysators    im Rührauto  klaven auf     220-230'    C erhitzt. Bei der  Aufarbeitung des vom Katalysator befreiten  Reaktionsproduktes mit Wasserdampf und       Umkristallisieren    des Rückstandes aus Me  thanol erhält man das     Carbolin.  



  Method of making a heteroeyclic connection. The present patent relates to a process for the preparation of a heterocyclic compound, characterized in that a mixture of tetrahydrocarboline of the formula
EMI0001.0006
    a hydrogen scavenging substance and a hydrogenation catalyst. - The carboline obtained in this way is known. 1s melts in the pure state at 2100 ° C. (see Chem. Zentralblatt 1924, 1st p. 2518).

    It is intended to be used as an intermediate in the manufacture of dyes and pharmaceutical products. <I> Example: </I> 30 parts of tetrahydrocarboline of the formula
EMI0001.0013
    are heated to 220-230 'C with 60 parts of phenol and 1 part of a hydrogenation catalyst in a stirred autoclave. The carboline is obtained when the reaction product freed from the catalyst is worked up with steam and the residue is recrystallized from methanol.
