Description

  

      Verfahren        zur    Herstellung     eines    neuen     synthetischen,        oestrogenen        Mittels.       Die vorliegende     Erfindung        betrifft    ein  Verfahren zur Herstellung eines neuen, syn  thetischen     oestrogenen        Mittels,    eines     substi-          tuierten        Triphenyläthylens    der Formel  
EMI0001.0014     
    Erfindungsgemäss     wird    diese neue Ver  bindung dadurch erhalten,

   dass man das       Triphenyläthylen    der Formel  
EMI0001.0017     
    nach der Auflösung in einem     inerten    orga  nischen     Lösungsmittel    mit der     mindestens          annähernd        äquimolekularen    Menge Brom zur  Umsetzung bringt.  



  Zweckmässig verwendet man einen ge  ringen Überschuss an Brom, beispielsweise  2 oder 5 % mehr als den     theoretischen    Wert.  Ein grosser Überschuss ist zu vermeiden, da  dies zu höher     bromierten    Produkten führen  würde.    Als zur Durchführung der Umsetzung       geeignete        Lösungsmittel    seien beispielsweise       Tetrachlorkohlenstoff,    Eisessig,     Nitrobenzol     und Chlorbenzol erwähnt.  



  Das     substituierte        Triphenyläthylen,    der       Ausgangsstoff    für das     erfindungsgemässe       Verfahren, kann leicht durch Wasserentzug  aus dem entsprechend     substituierten        Triphe-          nyläthanol,    z. B, durch Erhitzen desselben  mit einem     Dehydratisierungsmittel,    wie bei  spielsweise Schwefelsäure,     Acetylehlorid     oder     Phosphortribramid,        dargestellt    werden.  



  Das     substituierte        Triphenyläthanol    selbst  kann seinerseits durch     Grignard-Reaktion     aus einem geeignet substituierten     Desogy-          benzoin    und     p-Anisyl-    oder     p-Phenetyl-          Mab,onesiumbromid    erhalten werden. So kann  man z. B.     Desogyanisoin    und     p-Phenetyl-          Magnesiumbromid    verwenden.

   Eine beson  ders bequeme Darstellungsmethode besteht       darin,        dass    man     p-Äthoxy-p'-methoxy-benzo-          phenon    mit einem     Benzyl-Magnesiumhalo-          genid    umsetzt.  



  Die neue Verbindung stellt ein wirk  sames     oestrogenes    Mittel dar, das die uner  wartete Eigenschaft aufweist, dass es bei  der Einnahme durch den Mund wirksamer  ist, als wenn es durch     Injektion    eingeführt       wird.       Die Erfindung sei durch das     folgende          Beispiel,    in welchem die Teile     Gewichtsteile          bedeuten,    erläutert.         Beispiel:     16,5     Teile        a-p-Anisyl-a-p-phenetyl-ss-phe-          nyläthylen    werden in 150 Teilen Eisessig  gelöst.

   Diese Lösung wird bei     20-30     C ge  rührt und mit 8,2 Teilen Brom versetzt,  welches in     82    Teilen Eisessig gelöst wurde.      Nun     wird    das     Reaktionsgemisch    während  24 Stunden stehengelassen     und    hierauf mit  Wasser     verdünnt.    Der gebildete Niederschlag  stellt rohes     a-p-Anisyl-a-p-phenetyl-ss-phe-          nyl-bromäthylen    dar. Dieses wird aus     Äthyl-          alkohol    umkristallisiert, worauf es bei     78'C          schmilzt.     



  Der Ausgangsstoff, das     a-p-Anisyl-a-          p-phenetyl-P-phenyl-äthylen,        wird        vorteil=          haft    durch Kochen am     Rückfluss    von     a-p-          Anisyl-a-p-phenetyl-;B-phenyl-äthanol    mit  einem     Überschuss    an     Acetylchlorid    herge  stellt. Auf diese Weise     wird    dieses Produkt  in Form     einer    zähflüssigen Flüssigkeit er  halten, welche bei 15 mm Druck bei 240  bis 250 C siedet.



      Process for the preparation of a new synthetic, estrogenic agent. The present invention relates to a process for the preparation of a new, synthetic estrogenic agent, a substituted triphenylethylene of the formula
EMI0001.0014
    According to the invention, this new connection is obtained by

   that you get the triphenylethylene of the formula
EMI0001.0017
    after dissolution in an inert organic solvent with the at least approximately equimolecular amount of bromine to react.



  It is advisable to use a slight excess of bromine, for example 2 or 5% more than the theoretical value. A large excess should be avoided, as this would lead to higher brominated products. Examples of suitable solvents for carrying out the reaction are carbon tetrachloride, glacial acetic acid, nitrobenzene and chlorobenzene.



  The substituted triphenylethylene, the starting material for the process according to the invention, can easily be nylethanol by removing water from the correspondingly substituted triphenylethanol, eg. B, by heating the same with a dehydrating agent such as sulfuric acid, acetyl chloride or phosphorus tribramide, for example.



  The substituted triphenylethanol itself can in turn be obtained from a suitably substituted desogybenzoin and p-anisyl or p-phenetyl Mab, onesium bromide by Grignard reaction. So you can z. B. Use desogyanisoin and p-phenetyl magnesium bromide.

   A particularly convenient method of preparation consists in reacting p-ethoxy-p'-methoxy-benzophenone with a benzyl magnesium halide.



  The new compound is a potent estrogenic agent which has the unexpected property that it is more effective when taken by mouth than when introduced by injection. The invention is illustrated by the following example, in which the parts mean parts by weight. Example: 16.5 parts of a-p-anisyl-a-p-phenetyl-ss-phenylethylene are dissolved in 150 parts of glacial acetic acid.

   This solution is stirred at 20-30 C and treated with 8.2 parts of bromine, which was dissolved in 82 parts of glacial acetic acid. The reaction mixture is then left to stand for 24 hours and then diluted with water. The precipitate formed is crude a-p-anisyl-a-p-phenetyl-ss-phenyl-bromoethylene. This is recrystallized from ethyl alcohol, whereupon it melts at 78 ° C.



  The starting material, the ap-anisyl-a-p-phenetyl-P-phenyl-ethylene, is advantageously prepared by refluxing ap-anisyl-ap-phenetyl-; B-phenyl-ethanol with an excess of acetyl chloride . In this way, this product will be kept in the form of a viscous liquid which boils at 240 to 250 ° C. at 15 mm pressure.
