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.
