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.
