Description

  

  Verfahren zur Darstellung einer     Aminoverbindung    der     Chinolinreihe.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung einer     Aminover-          bindung    der     Chinolinreihe,    dadurch gekenn  zeichnet, dass man die     Chinolin-4-sulfosäur,e     mit     1-Diäthylamino-4-amirropentan     
EMI0001.0008     
    in Gegenwart von Wasser auf höhere Tem  peraturen erhitzt.  



  Das so erhaltene neue Kondensationspro  dukt der Formel:  
EMI0001.0009     
    ist ein fastfarbloses viskoses Öl, dessen Pik  rat     grünstichgelbe    Nadeln vom Schmelzpunkt    155-157   C bildet. Es soll als Zwischen  produkt zur Herstellung von Farbstoffen und  pharmazeutischen Produkten Verwendung fin  den.  



       Beispiel:     12 Teile     Chinolin-4-sulfosäure    werden mit  18 Teilen     1-Diäthylamino-4-aminopentarr     
EMI0001.0014     
    und 40 Teilen Wasser 16 Stunden auf etwa  135   C erhitzt. Das nach dem Erkalten als  dickflüssiges Öl abgeschiedene Reaktionspro  dukt wird durch Ausschütteln mit Äther iso  liert, der Ätherrückstand wird hierauf mit       Wasserdampf    behandelt und erneut in Äther  aufgenommen.



  Process for the preparation of a quinoline series amino compound. The present patent relates to a process for the preparation of an amino compound of the quinoline series, characterized in that the quinoline-4-sulfonic acid is mixed with 1-diethylamino-4-amirropentane
EMI0001.0008
    heated to higher temperatures in the presence of water.



  The resulting new condensation product of the formula:
EMI0001.0009
    is an almost colorless viscous oil, the pic rat of which forms greenish yellow needles with a melting point of 155-157 C. It is intended to be used as an intermediate product in the manufacture of dyes and pharmaceutical products.



       Example: 12 parts of quinoline-4-sulfonic acid are mixed with 18 parts of 1-diethylamino-4-aminopentar
EMI0001.0014
    and 40 parts of water heated to about 135 ° C. for 16 hours. The reaction product, which is deposited as a viscous oil after cooling, is isolated by shaking it out with ether, the ether residue is then treated with steam and taken up again in ether.
