Description
Verfahren zur Herstellung einer in 4-Stellung eine basisch substituierte Aminogruppe enthaltenden Chinolinverbindung. Das Hauptpatent betrifft ein Verfahren zur Darstellung einer therapeutisch wert vollen Chinolinverbindung.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer in 4- Stellung eine basisch substituierte Amino- gruppe enthaltenden Verbindung. Das Ver fahren ist dadurch gekennzeichnet, dass man. 4-Chlor-7-jodchinolin mit 1-Diäthylamino-4- aminopentan zu 4-(5'-Diäthylaminopentyl-2'- amino)-7-jodchinolin umsetzt.
Die Umset zung erfolgt zum Beispiel durch Erwärmen der genannten Ausgangsstoffe auf höhere Temperaturen, zum Beispiel auf etwa 150 bis<B>160'.</B> Die Aufarbeitung der Reaktions mischung erfolgt zum Beispiel in üblicher Weise. Das so erhaltene Produkt schmilzt, aus Äther-Petroläther umkristallisiert, bei 12111.
Das neue Produkt soll therapeutische An wendung finden.
<I>Beispiel:</I> 28,9 g 4-Chlor-7-jodchinolin vom Schmelz punkt 101 werden mit 81,6 g 1-Diäthyl- amino-4-aminopentan 15 Stunden in einem Ölbad von 150 bis<B>160'</B> erhitzt. Die erkal tete Schmelze wird in verdünnter Essigsäure gelöst und filtriert. Dann -wird mit Natron lauge alkalisch gemacht und die abgeschie dene Base in Äther aufgenommen, mit Was ser gewaschen und mit Pottasche getrocknet. Das 4-(5'-Diäthylaminopentyl-2'-amino)- 7- jodchinolin wird aus Äther-Petroläther um kristallisiert; es schmilzt bei 121'.
Process for the preparation of a quinoline compound containing a basic substituted amino group in the 4-position. The main patent relates to a method for preparing a therapeutically valuable quinoline compound.
The subject of the present patent is a process for the preparation of a compound containing a basic substituted amino group in the 4-position. The process is characterized in that one. 4-chloro-7-iodoquinoline is reacted with 1-diethylamino-4-aminopentane to give 4- (5'-diethylaminopentyl-2'-amino) -7-iodoquinoline.
The reaction takes place, for example, by heating the starting materials mentioned to higher temperatures, for example to about 150 to 160 '. The reaction mixture is worked up, for example, in the customary manner. The product thus obtained melts, recrystallized from ether-petroleum ether, at 12111.
The new product is intended to be used therapeutically.
<I> Example: </I> 28.9 g of 4-chloro-7-iodoquinoline with a melting point of 101 are mixed with 81.6 g of 1-diethylamino-4-aminopentane in an oil bath from 150 to <B> for 15 hours 160 'heated. The cooled melt is dissolved in dilute acetic acid and filtered. Then - is made alkaline with sodium hydroxide solution and the deposited base is taken up in ether, washed with water and dried with potash. The 4- (5'-diethylaminopentyl-2'-amino) - 7-iodoquinoline is crystallized from ether-petroleum ether; it melts at 121 '.
