Description

  

  Verfahren zur Darstellung eines neuen Esters.         Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines neuen  Esters, welches dadurch     gekennzeichnet    ist,  dass man auf     44,5        -Androstenol    - (17) - an - (3)  eine Verbindung einwirken lässt, die das  Radikal der Chloressigsäure enthält,     wie    z. B.  die freie Säure selbst, ihre Ester,     Halogenide     oder ihr     Anhydrid.     



  Der so gewonnene     V4,6-Androstenol-(17)-          on-(3)-chloressigsäureester    der Formel  
EMI0001.0010     
    hat den F. 123 bis 124'. Derselbe kann  durch     Umsetzung    mit primären und sekun  dären     Aminen    in     Verbindungen    übergeführt  werden, die in der Form ihrer Salze wasser  löslich sind.  



  Die neue     Verbindung    soll therapeutische  Verwendung finden oder als Zwischen-    Produkt zur Herstellung     therapeutisch    ver  wendbarer Stoffe dienen.  



       Beispiel:          Ein    Gemisch von 1,1 Teilen     Testosteron     und 1,2 Teilen     Chloressigsäureanhydrid    wird  einige Zeit auf 110       erwärmt.    Nach dem  Erkalten wird die Schmelze in     wässerigem     Aceton gelöst und     durch    Wasserzugabe zur  Kristallisation gebracht. Die Kristalle wer  den     abfiltriert,    mit verdünnter     Sodalösung     und Wasser gewaschen und getrocknet.

   Zur  weiteren     Reinigung    kann der     d4,5-An.drostenol-          (17)-on-(3)-chloressigsäureester    aus     Hegan     umkristallisiert werden. Er     schmilzt    bei 123  bis 124'. Derselbe kann durch     Umsetzung,     z. B. mit     Diäthylamin,    in eine     Verbindung     übergeführt werden, die zum Beispiel als     Hy-          drochlorid    wasserlöslich ist.



  Process for the preparation of a new ester. The subject of the present patent is a process for the preparation of a new ester, which is characterized in that a compound is allowed to act on 44,5 -androstenol - (17) - to - (3) which contains the radical of chloroacetic acid, such as . B. the free acid itself, its esters, halides or its anhydride.



  The V4,6-androstenol- (17) -on- (3) -chloroacetic acid ester of the formula obtained in this way
EMI0001.0010
    has the F. 123 to 124 '. The same can be converted by reaction with primary and secondary amines in compounds which are water-soluble in the form of their salts.



  The new compound should find therapeutic use or serve as an intermediate product for the production of therapeutically ver usable substances.



       Example: A mixture of 1.1 parts testosterone and 1.2 parts chloroacetic anhydride is heated to 110 for some time. After cooling, the melt is dissolved in aqueous acetone and crystallized by adding water. The crystals who filtered off, washed with dilute soda solution and water and dried.

   For further purification, the d4,5-an.drostenol- (17) -one- (3) -chloroacetic acid ester can be recrystallized from Hegan. It melts at 123 to 124 '. The same can be done by implementation, e.g. B. with diethylamine, can be converted into a compound that is water-soluble, for example as hydrochloride.
