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-sulfosäure     mit asymmetrischem     Diäthyl-äthyleiidiamiii          (C2H5)2N-CH2-CH2NH2    in Gegenwart von  Wasser auf höhere Temperaturen erhitzt.  



  Das so erhaltene neue Kondensations  produkt der Formel  
EMI0001.0009     
    ist ein fast farbloses viskoses Öl, dessen     Pikrat     bei 189-190   C schmilzt. Es soll als Zwi  schenprodukt zur Herstellung von Farbstoffen  und pharmazeutischen Produkten Verwendung  finden.    <I>Beispiel:</I>    12 Teile     Chinolin-4-sulfosäure    werden mit  12 Teilen asymmetrischem     Diäthyl-äthylen-          diamin        (C2H5)2N--CH2-CH2NH2   <B>und 40</B>  Teilen Wasser 16 Stunden auf etwa 135   C  erhitzt. Das nach dem Erkalten als dick  flüssiges Öl abgeschiedene Reaktionsprodukt  wird durch Ausschütteln mit Äther isoliert,  der Ätherrückstand wird hierauf mit Wasser  dampf behandelt und erneut in Äther auf  genommen.



  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 heated to higher temperatures with asymmetrical diethyl-ethyleiidiamiii (C2H5) 2N-CH2-CH2NH2 in the presence of water.



  The new condensation product of the formula obtained in this way
EMI0001.0009
    is an almost colorless viscous oil, the picrate of which melts at 189-190 C. It should be used as an inter mediate product for the production of dyes and pharmaceutical products. <I> Example: </I> 12 parts of quinoline-4-sulfonic acid are mixed with 12 parts of asymmetrical diethylethylene diamine (C2H5) 2N - CH2-CH2NH2 and 40 parts of water for about 16 hours 135 C heated. The reaction product deposited as a thick liquid oil after cooling is isolated by shaking it out with ether, the ether residue is then treated with water vapor and taken up again in ether.

PATENTANSPRUCH: Verfahren zur Darstellung einer Amino- verbindung der Chinolinreihe, dadurch ge kennzeichnet, dass man die Chinolin-4-sulfo- säure mit asymmetrischem Diäthyl-äthylen- diamin (C2H5)2N-CH2-CH21VH2 in Gegen wart von Wasser auf höhere Temperaturen erhitzt. Das so erhaltene neue Kondensations produkt der Formel EMI0002.0001 ist ein fast farbloses viskoses Öl, dessen Pikrat bei 180-190 C schmilzt. PATENT CLAIM: Process for the preparation of an amino compound of the quinoline series, characterized in that the quinoline-4-sulfonic acid is heated to higher temperatures with asymmetrical diethylethylene diamine (C2H5) 2N-CH2-CH21VH2 in the presence of water . The new condensation product of the formula obtained in this way EMI0002.0001 is an almost colorless viscous oil, the picrate of which melts at 180-190 C. Es soll als Zwischenprodukt zur Herstellung von Farbstoffen und pharmazeutischen Produkten Verwendung finden. It is intended to be used as an intermediate in the manufacture of dyes and pharmaceutical products.
