Description
Verfahren zur Darstellung eines P-alkyl-substituierten Aethylamin-Derivätes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Darstellung von ss-Tri- isoamylä.thylamin, das dadurch gekennzeich net ist, dass man Tri-isoamyl-acetonitril mit Wasserstoff behandelt. Die neue Verbindung soll als Arzneimittel Verwendung finden.
Für ihre technische Herstellung hat sich am vorteilhaftesten erwiesen, das genannte Nitril in Gegenwart von zweckmässig auf Trägern niedergeschlagenen Nichtedelmetall- Katalysatoren, vor allem von auf Kieselgur niedergeschlagenen Nickelkatalysatoren, mit Wasserstoff unter Druck bei erhöhter Tem peratur, z. B. bei 120 bis 140 , zu reduzie ren. Verwendet man sogenannte Raney-Kata- lysatoren, die erhalten werden können durch Herauslösen des Aluminiums aus einer Nickel-Aluminium-Legierung, z.
B. nach dem Verfahren des amerikanischen Patentes Nr. 1915473, so lässt sich die Reduktion auch bei niederen Temperaturen, z. B. schon bei 7 0 durchführen. <I>Beispiel:</I> 60 Teile Tri - isoamylacetonitril vom K.P" <B>155'</B> und 4 Teile Nickelkatalysator auf Kieselgur, der bei 4501 1 Stunde redu ziert war, wurden, im Hochdruckautoklaven mit 100 Atü Wasserstoff beschickt. Bei einer Temperatur von 125 wurde in 2 Stunden die theoretische Wasserstoffmenge aufge nommen.
Nach Abtrennung des Katalysators durch Filtration wurde das Reaktionspro- dukt durch eine 30 cm hohe Kolonne frak tioniert. Man erhält eine Ausbeute über 90 (d. Theorie) an Tri-isoamyläthylamin vom K.P, 152 . Das Chlorhydrat, weisse, sich fettig anfühlende Kristalle, schmilzt bei 69 .
Die spasmolytisehe Wirkung des Chlor hydrats ist 300mal so gross als die des Novo- cain-HCl.
Die Reduktion des Nitrils ist mit gleicher Ausbeute auch durchführbar, wenn man es in einem Schüttelgefäss (oder Rührautokla- ven) unter Zusatz von 3 Teilen Raney- Nickelkatalysator bei 60 bis 70 unter einem Druck von 30 cm Wassersäule mit reinem Wasserstoff behandelt, solange noch Wasser stoff aufgenommen wird. Das Reaktionspro dukt wird dann vom Katalysator getrennt und wie oben gereinigt.
Process for the preparation of a P-alkyl-substituted ethylamine derivative. The subject of the present patent is a process for the preparation of ss-tri-isoamylä.thylamin, which is characterized in that tri-isoamyl-acetonitrile is treated with hydrogen. The new compound is said to be used as a drug.
For their industrial production has proven to be most advantageous, said nitrile in the presence of suitably deposited on supports base metal catalysts, especially precipitated nickel catalysts on kieselguhr, with hydrogen under pressure at elevated tem perature, eg. B. at 120 to 140, to reduce ren. If you use so-called Raney catalysts, which can be obtained by dissolving the aluminum from a nickel-aluminum alloy, z.
B. according to the method of American patent no. 1915473, the reduction can also be carried out at low temperatures, e.g. B. perform at 7 0. <I> Example: </I> 60 parts of tri-isoamylacetonitrile from KP "155" and 4 parts of nickel catalyst on kieselguhr, which was reduced at 4501 for 1 hour, were in a high pressure autoclave with 100 atmospheres of hydrogen At a temperature of 125, the theoretical amount of hydrogen was taken up in 2 hours.
After the catalyst had been separated off by filtration, the reaction product was fractionated through a 30 cm high column. A yield of over 90 (d. Theory) of tri-isoamylethylamine from K.P. 152 is obtained. The hydrochloride, white, greasy-feeling crystals, melts at 69.
The spasmolytic effect of the chlorohydrate is 300 times greater than that of the novocaine HCl.
The reduction of the nitrile can also be carried out with the same yield if it is treated with pure hydrogen in a shaking vessel (or stirred autoclave) with the addition of 3 parts Raney nickel catalyst at 60 to 70 under a pressure of 30 cm water column, while still water substance is absorbed. The reaction product is then separated from the catalyst and purified as above.
