Description
Verfahren zur Herstellung von aal-D1-(p-n-butyrogyphenyl)-a,a'-diäthyl-äthan. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung des oestrogen wirksamen, als Heilmittel und als Zwischen- produkt zur Herstellung von Heilmitteln ver wendbaren a,a'-Di-(p-n-butyroxyphenyl)- a,a'-diäthyl-äthans, das dadurch gekennzeich net ist, dass man das a,a'-Di-(p-n-butyroxy- phenyl) <I>-</I> a,
a'- diäthyl- äthen der Einwirkung hydrierender Mittel unterwirft, wodurch die aliphatische Doppelbindung des Moleküls abgesättigt wird.
Zu diesem Zweck kann das Ausgangs material in. einem geeigneten Lösungsmittel, beispielsweise in Äthanol, Methanol, Aceton oder Eisessig, der Einwirkung von Wasser stoff unterworfen werden, vorzugsweise in Gegenwart eines Hydrierungskatalysators. Als Katalysatoren eignen sich besonders Edelmetallkatalysatoren, wie Platinoxyd oder Palladiumkatalysatoren. Mit diesen Mit teln lässt sich die Hydrierung bereits bei Zimmertemperatur durchführen.
Das Verfah rensprodukt wird in fast quantitativer Aus- beute erhalten. Es ist mit dem nach Patent Nr. 23'2;49;1 erhältlichen Produkt identisch. Beispiel:
Man behandelt eine Lösung von 2<I>g</I> a,ä - Di- (p -n=-butyrogyphenyl)-a,a'-diäthyl-äthen in Aceton bei Zimmertemperatur in Gegen wart eines Palladiumkatalysators mitWasser- Stoff. Nach Aufnahme etwa eines Mol Was serstoff bleibt die Reaktion stehen. Man fil triert vom Katalysator ab, dampft das Aceton ab und kristallisiert den Rückstand aus Methanol um.
Das so erhaltene a,a\-Di-(p-n-butyroxy- phenyl)-a,a'-diäthyl-äthan fällt in einer Aus beute von 1,8 g an und bildet farblose Kri stalle vom Smp. 105-108 .
Process for the production of eel-D1- (p-n-butyrogyphenyl) -a, a'-diethyl-ethane. The subject of the present patent is a process for the preparation of the estrogenic, a, a'-di- (pn-butyroxyphenyl) - a, a'-diethyl-ethane, which can be used as a remedy and as an intermediate for the manufacture of remedies it is indicated that the a, a'-di- (pn-butyroxyphenyl) <I> - </I> a,
a'-diethyl ethene is subjected to the action of hydrogenating agents, whereby the aliphatic double bond of the molecule is saturated.
For this purpose, the starting material can be subjected to the action of hydrogen in a suitable solvent, for example in ethanol, methanol, acetone or glacial acetic acid, preferably in the presence of a hydrogenation catalyst. Noble metal catalysts, such as platinum oxide or palladium catalysts, are particularly suitable as catalysts. With these means, the hydrogenation can be carried out at room temperature.
The process product is obtained in an almost quantitative yield. It is identical to the product available under Patent No. 23'2; 49; 1. Example:
A solution of 2 g a, a-di- (p -n = -butyrogyphenyl) -a, a'-diethyl-ethene in acetone is treated at room temperature in the presence of a palladium catalyst with water. After absorbing about one mole of hydrogen, the reaction stops. The catalyst is filtered off, the acetone is evaporated and the residue is recrystallized from methanol.
The a, a \ -di (p-n-butyroxyphenyl) -a, a'-diethyl-ethane obtained in this way is obtained in a yield of 1.8 g and forms colorless crystals of melting point 105-108.
