  Die Ausgangsstoffe werden z. B. erhalten  aus     1-geto-2-äthyl'-7-methoxy-1,2,3,4-tetra-          hydro-phenanthrenen,    die     in        2-Stellung    einen  durch     Hydrolyse    in die     freie        Carboxylgruppe          übenführbaren        Substituentenaufweisen,    durch       Grignardierung    mit einem     Äthylmagnesium-          halogenid,        Wasserabspaltung        aus    dem so er  haltenen 1-     Oxy    -1,

  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new oxyhydrophenanthrene derivative can be obtained by using a 1,2-diethyl'-7-methoxy-1,2,3,4-tetrahydTo-phenanthrene,

      the substituent in the 2-position which can be converted into the free carboxyl group by hydrolysis, e.g. B. contains an esterified carboxyl group, treated with hydrolyzing agents to form a free carboxyl group.



  The as yet unknown end product of the process, the 1,2-di, ethyl-7-methoxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid of F. 183-185, shows both parenteral and an extraordinarily high estrogenic effect even with oral application. It should be used therapeutically or serve as an intermediate product for the establishment of therapeutically usable connections.



  For the conversion of the substituent in the 2-position into the free carboxyl group, inorganic bases, such as alkali or eudalkali hydroxides, are used, for example.



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

  2-diethyl-7-methoxy-1,2,3,4-tetrahydrophenanthrene derivative and subsequent hydrogenation of the double bond formed.

      <I> Example: </I> 7 parts by weight of 1,2-diethyl-7-methoxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester of F. 69-70 and the formula
EMI0001.0069
    be in one; Mixture of 14 parts by weight of potassium hydroxide, 3 parts by volume of water and 10 parts by volume of alcohol heated to 160.

    After the alcohol has evaporated, the potassium salt of the carboxylic acid crystallizes out in the warmth. This is absorbed in <B> 100 </B> parts by volume of water, whereupon the poorly soluble galium salt separates out after a short time.

   By decomposition with dilute hydrochloric acid, the oes.trogenically active 1,2-diethyl-7-methoxy-1,2,3,4-tetrahydro-phenantthene-2-carboxylic acid of the formula is obtained
EMI0001.0085
    obtained, which melts at 183-185 after pouring from methanol.



  The starting material is obtained z. B. as follows: 12.5 parts by weight of 1-geto-2-ethyl-7-methoxy -1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester is left with a Grignard solution, prepared from 1.05 Ge - parts by weight of magnesium and 5 parts by weight of ethyl bromide, react,

   Boils 8 parts by weight of the 1-oxy-1,2-diethyl 1,2,3,4 - tetrahydro - phenanthrene - 2: - carboxylic acid methyl at the least from F.

       131-132 for the purpose of splitting off water in a solution of 0.3 part by weight of iodine in 40 parts by volume of chloroform. and hydrogenated 1 part by weight of the Ethyliidenverbindungen in 30 parts by volume of alcohol in the presence of 0.1 part by weight of a platinum catalyst to 1,2-diethyl-7-methoxy-1,2,3,4-tstrahydro-phenanthrene-2-carboxylic acid methyl ester from F.
