Description
Verfahren zur Herstellung eines oestrogenen Stoffes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung des oestrogen wirksamen, als Arzneimittel und Zwischen produkt zur Herstellung von Arzneimitteln verwendbaren a. a'-Di-(p-n-butyroxy-phenyl)- a <I>. ä</I> -di-äthyl-äthans, das dadurch gekenn zeichnet ist, dass man auf<I>a . ä</I> -Di-(p-oxy- phenyl)-a .
a'-di-äthyl-äthan ein n-butyrylie- rendes Mittel einwirken lässt.
Als n-butyrylierende Mittel eignen sich n-Buttersäure, ihr Anhydrid oder n-Butter- säurehalogenide.
Beispiel: Eine Lösung von 5 g a . a'- Di - (p - oxy- phenyl)-a . a'-di-äthyl-äthan in 50 cm@ trok- kenem Pyridin wird mit 7 g n-Buttersäure- anhydrid vermischt und während 2 Tagen bei Zimmertemperatur stehen gelassen. Das Py- ridin wird dann im Vakuum entfernt und der feste Rückstand in Äther aufgenommen.
Die ätherische Lösung wird zunächst mit 5 % iger Natronlauge, dann mit Wasser ausgeschüt telt, getrocknet und eingedampft. Das zurück- bleibende Di-n-butyrat liefert nach Umkri- stallisieren aus Methylalkohol farblose Kri stalle vom Smp. 105 bis 108 . Die oestrogene Wirkung an der kastrierten weiblichen Ratte beträgt etwa 1,8 y.
Process for the production of an estrogenic substance. The subject of the present patent is a process for the production of the estrogenic, usable as a medicament and intermediate product for the production of medicaments a. a'-di- (p-n-butyroxy-phenyl) - a <I>. ä </I> -di-äthyl-äthans, which is characterized by the fact that one clicks on <I> a. ä </I> -Di- (p-oxyphenyl) -a.
a'-di-ethyl-ethane allows an n-butyrylating agent to act.
Suitable n-butyrylating agents are n-butyric acid, its anhydride or n-butyric acid halides.
Example: A solution of 5 g a. a'- di - (p - oxyphenyl) -a. a'-Di-ethyl-ethane in 50 cm @ dry pyridine is mixed with 7 g of n-butyric anhydride and left to stand for 2 days at room temperature. The pyridine is then removed in vacuo and the solid residue is taken up in ether.
The ethereal solution is first extracted with 5% sodium hydroxide solution and then with water, dried and evaporated. The remaining di-n-butyrate, after recrystallization from methyl alcohol, gives colorless crystals with a melting point of 105 to 108. The estrogenic effect on the castrated female rat is about 1.8 y.
