      Verfahren    zur Herstellung eines neuen      xyhydrophenanthren-Derivates.       Es wurde     gefunden,    dass man zu einem  neuen     Oxyhydro@phenanthren-Derivat    gelan  gen kann, wenn     man    ein     1-Methyl-2-äthy        1-7-          methoxy-1,2,3,4-tetrahydro-phenanthren,    das  in     2-Stellung    einen durch Hydrolyse in die  freie     Carboxylgruppe        überführbaren        Substi-          t:uenten,    z.

   B.     eine        veresterte        Canboxylgruppe,     enthält, zwecks Bildung einer freien     Carb-          oxylgruppe    mit     hydrolysierenden    Mitteln be  handelt.  



  Das noch nicht bekannte Endprodukt des  Verfahrens, die     1-Methyl'-2-,äthyl-7-methoxy-          1,2,3,4-tetrahydro-phenanthren-2-carbonsäure     vom F. 173-174 , zeigt     sowohl    bei     pa.r-          enteraler    als auch bei oraler Applikation eine  ausserordentlich hohe     oestrogene    Wirkung. Es  soll     therapeutische        Verwendung    finden oder  als Zwischenprodukt zur Herstellung thera  peutisch     verwendbarer    Verbindungen dienen.  



  Für die Überführung des     Substituenten     in     2-Stellung    in die freie     Carboxylgruppe     verwendet man     beispielsweise        anorganische     Basen, wie Alkali- oder     Erdalkalihydroxyde.     



  Die Ausgangsstoffe werden z.

Nach dem Verdampfen des Alkohols kristalli  siert noch     in-der    Wärme das Kaliumsatz     der          Carbonsäum        ausi.    Dieses nimmt man in 100       Volumteilen        Wasser    auf,

   worauf sich nach  kurzer Zeit das schwer lösliche     Kaliumsalz          ausscheidet.    Durch Zersetzen mit     verdünnter     Salzsäure     wind    daraus die     oestrogen    wirksame       1-Methyl    - 2 -     äthyl    - 7 -     methoxy-1,2,3,4-tetra-          hydro-p.henanthren-2-carbonsäure    der     Formel

      Process for the preparation of a new xyhydrophenanthrene derivative. It has been found that a new Oxyhydro @ phenanthrene derivative can gelan conditions if a 1-methyl-2-ethy 1-7-methoxy-1,2,3,4-tetrahydro-phenanthrene, which in 2- Position of a substituent which can be converted into the free carboxyl group by hydrolysis: uenten, z.

   B. contains an esterified canboxyl group, for the purpose of forming a free carboxyl group with hydrolyzing agents.



  The not yet known end product of the process, the 1-methyl'-2-, ethyl-7-methoxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid of F. 173-174, shows both in pa. An extremely high estrogenic effect, both enterally and orally. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically useful compounds.



  To convert the substituent in the 2-position into the free carboxyl group, for example, inorganic bases such as alkali or alkaline earth metal hydroxides are used.



  The starting materials are z. B. obtained from 1-keto-2-ethyl-7-methoxy-1,2,3,4-tetra-hydro-phenanthrenes which have a substituent in the 2-position which can be converted into the free carboxyl group by hydrolysis Gnignardation with a methyl magnesium halide, elimination of water from the 1-methyl-lo obtained in this way:

  xy-2-ethyl-7-m @ ethoxy-1,2,3,4-tetrahydro-phenanthrene derivative and subsequent hydrogenation of the double bond formed. <I> Example: </I> 3.3 parts by weight of 1-methyl-2-ethyl-7-methoxy -1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester of the formula

    are in a mixture of 16.5 weight-.

    share potassium hydroxide, 5 parts by volume of water and 10 parts by volume of alcohol heated to 160. After the alcohol has evaporated, the potassium carbonate of the carbonate crystallizes in the heat. This is taken up in 100 parts by volume of water,

   whereupon the poorly soluble potassium salt precipitates after a short time. By decomposing it with dilute hydrochloric acid, the estrogenically active 1-methyl-2-ethyl-7-methoxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid of the formula is obtained
EMI0001.0080
    obtained which melts at 173-174 after redissolution from methanol.



  The starting material is obtained z. B. as follows: 12 parts by weight of 1-keto-2-ethyl-7-methoxy -1,2,3; 4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester is left with a Grignard solution prepared from 1.25 parts by weight of magnesium and 5 parts by volume of methyl iodide, react, boil 3 parts by weight of the 1-methyl-l-oxy-2-ethyl-1,2,3 thus obtained,

  4 - tetrahydro - phenanthrene - 2 - carboxylic acid methyl ester for the purpose. Elimination of water in a solution of 0.3 part by weight of iodine in 40 parts by volume of chloroform and hydrogenates 1 part by weight of the methylene compound in 30 parts by volume of alcohol in the presence of 0,
