Description
Verfahren zur Herstellung von a,a'-1)i-(p-propogyphenyl)-a,a'-clläthyl-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,ä -Di-(p-propoxyphenyl)-a,ä -di- äthyl-äthans, das dadurch gekennzeichnet ist.
dass man das a,a'-Di-(p-propoxyphenyl)- a,a'-diäthyl-äthen der Einwirkung hydrieren der Mittel unterwirft, wodurch die alipha- t-ische Doppelbindung des Molekiils abge- sättigt wird.
Zu diesem Zwecke kann das Ausgangs material in einem geeigneten Lösungsmittel. beispielsweise in Äthanol, Methanol, Aceton oder Eisessig, c',r Eir m@irkung von Wasser stoff unterworfen werden, vorzugsweise in Gegenwart eines Hydrierungskatalysators. Als Katalysatoren eignen sieh besonders Edelmetallkatalysatoren, wie Platinoxyd- oder Palladium-Katalysatoren. Mit diesen Mitteln 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. 232489 erhältlichen Produkt identisch. <I>Beispiel:</I> Man behandelt eine Lösung von 2<I>g</I> a,a'- Di- (p - propoxyphenyl) - a,a'- diäthyl-äthen iu Aeeton bei Zimmertemperatur in CTegenv#art eines Palladiumkatalysators mit Wasserstoff.
Nach Aufnahme etwa eines Mol Wasserstoff bleibt die Reaktion stehen. Man filtriert vom Katalysator ab, dampft das Aceton ab und kristallisiert den Rückstand aus Methanol um.
Das so erhaltene a,ä -Di-(p-propoxyphe- nyl)-a,a'-diäthyl-äthan fällt in Form farb loser kleiner Stäbchen in einer Ausbeute von 1,8 g an schmilzt bei 125 .
Process for the preparation of a, a'-1) i- (p-propogyphenyl) -a, a'-cllethyl-ethane. The subject of the present patent is a process for the production of the estrogenically active, as a medicament and as an intermediate product for the production of medicaments usable a, ä -di (p-propoxyphenyl) -a, ä -di-ethyl-ethane, which thereby is marked.
that the a, a'-di- (p-propoxyphenyl) -a, a'-diethyl-ethene is subjected to the action of hydrogenating the agent, whereby the aliphatic double bond of the molecule is saturated.
For this purpose, the starting material can be in a suitable solvent. for example in ethanol, methanol, acetone or glacial acetic acid, c ', r Eir m @ action of hydrogen are subjected, preferably in the presence of a hydrogenation catalyst. Particularly suitable catalysts are noble metal catalysts, such as platinum oxide or palladium catalysts. With these agents, 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. 232489. <I> Example: </I> A solution of 2 <I> g </I> a, a'-di- (p-propoxyphenyl) -a, a'-diethyl-ethene iu acetone is treated at room temperature in CTegenv #type of a palladium catalyst with hydrogen.
After absorbing about one mole of hydrogen, the reaction stops. The catalyst is filtered off, the acetone is evaporated off and the residue is recrystallized from methanol.
The a, ä -di (p-propoxyphenyl) -a, a'-diethyl-ethane obtained in this way falls in the form of colorless small rods in a yield of 1.8 g and melts at 125.
