Description
Verfahren zur Darstellung eines basischen Äthers. Gegenstand vorliegenden Patentes ist ein Verfahren zur Darstellung eines basischen Äthers. Das Verfahren ist. dadurch gekenn zeichnet, dass man eine Verbindung der Formel
EMI0001.0002
auf eine Verbindung der Formel
EMI0001.0003
worin X und Y zwei reaktionsfähige, mit. Aus nahme eines in einem von ihnen enthaltenen Sauerstoffatoms, sich bei der Reaktion abspal tende Reste bedeuten, einwirken lässt.
Die erhaltene neue Verbindung, der n-Pro pyl-cycloheptyl-carbin-p-dimethylamino-äthyl- äther, siedet bei 142-148 unter 12 mm Druck. Sie soll therapeutische Verwendung finden. <I>Beispiel:</I> Zu einer Suspension von 4 Teilen pulveri siertem Natriumamid in 60 Teilen absolutem Benzol werden 17,0 Teile n-.Propyl-cyclohep- tyl-carbinol zugetropft und 1. Stunde bei 60 gerührt. Dann werden 10,8 Teile ss-Dimethyl- amino-äthylchlorid zugegeben und das Ganze 5 Stunden unter Rückfluss und Rühren er hitzt.
Nach dem Abkühlen wird mit Wasser versetzt und mit 10o/oiger Salzsäure mehrmals ausgeschüttelt. Die vereinigten salzsauren Aus züge werden mit Pottasche alkalisch gestellt, die ausgeschiedene Base in Äther aufgenom- men, die Ätherlösung mit konzentrierter Pott asche gewaschen, über Natriumsulfat getrock net und der Äther abgedampft. Der als Rück stand erhaltene basische Äther siedet bei 1.42 bis l48 unter 12 mm Druck.
Zum gleichen Endprodukt gelangt man auch, wenn man einen reaktionsfähigen Ester des n-Propyl-cycloheptyl-carbinols, z. B. ein Halogenid, in Gegenwart säurebindender Mit tel mit ss-Dimethylamino-äthanol zur Umset zung bringt.
Process for the representation of a basic ether. The subject of the present patent is a method for the preparation of a basic ether. The procedure is. characterized in that there is a compound of the formula
EMI0001.0002
to a compound of the formula
EMI0001.0003
where X and Y are two reactive, with. With the exception of an oxygen atom contained in one of them, which means residues which split off during the reaction, can act.
The new compound obtained, the n-propyl-cycloheptyl-carbine-p-dimethylamino-ethyl ether, boils at 142-148 under 12 mm pressure. It should find therapeutic use. Example: 17.0 parts of n-propyl-cycloheptyl-carbinol are added dropwise to a suspension of 4 parts of powdered sodium amide in 60 parts of absolute benzene and the mixture is stirred at 60 for 1 hour. Then 10.8 parts of β-dimethylamino-ethyl chloride are added and the whole thing is heated under reflux and stirring for 5 hours.
After cooling, water is added and the mixture is extracted several times with 10% hydrochloric acid. The combined hydrochloric acid extracts are made alkaline with potash, the precipitated base is taken up in ether, the ether solution is washed with concentrated potash, dried over sodium sulphate and the ether is evaporated. The basic ether obtained as residue boils at 1.42 to 148 under 12 mm pressure.
The same end product is also obtained if a reactive ester of n-propyl-cycloheptyl-carbinol, eg. B. a halide, in the presence of acid-binding agents with ss-dimethylamino-ethanol for implementation.
