  Als     Hydrierungsmittel    verwendet man bei  spielsweise katalytisch angeregten Wasser  stoff in Gegenwart von Katalysatoren, wie  z. B. Platin, Palladium, Nickel und derglei  chen oder deren Oxyden oder Niederschlägen  auf geeigneten Trägern.

      process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new oxyhydrophenanthrene derivative can be obtained if a 1-ethylidene-2-methyl -1,2,3,4-tetrahydro-phenant.hrene-2-carboxylic acid, in the 7-position by hydrogenation convertible into the hydroxyl substituents such.

   B. contains a benzyl ether or triphenylmethyl ether group, converted into 1-ethyl-2-methy 1-7-oxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid by hydrogenation. The hitherto unknown end product of the process of F. 2041) shows an extraordinarily high estrogenic effect both on parenteral and on oral administration. It should find therapeutic use or as an intermediate.

    serve to produce therapeutically useful compounds.



  The hydrogenating agent used is, for example, catalytically excited hydrogen in the presence of catalysts, such as. B. platinum, palladium, nickel and the like surfaces or their oxides or precipitates on suitable carriers.



  The starting materials are z. B. obtained from 1-keto-2-methyl-1,2,3,4-tetrahydro-pheii- anthrene-2-carboxylic acid esters which contain a substituent in the 7-position which can be converted into the hydroxyl group by hydrogenation Grignardation with an ethyl magnesium halide, elimination of water from the carbinol obtained and saponification of the carboxylic acid ester group. <I> example:

  </I> 1 part by weight of 1-ethylidene-2-methyl-7-benzyloxy ^ -1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid of the formula
EMI0001.0047
    is shaken under hydrogen in 10 parts by volume of 0.5 @ strength aqueous sodium hydroxide solution in the presence of 1 part by weight of a nickel catalyst.

   After the amount of hydrogen calculated for 2 molar equivalents has been taken up, the catalyst is filtered off, the oxy acid is precipitated using mineral acid and suction filtered. The filter residue provides, after recrystallization from ethyl acetate, the estrogenically active 1-ethyl-2-methy 1-7-oxy -1,2,3,4-tetra-hydro-phenanthrene-2-carboxylic acid of F. 204 and the formula
EMI0001.0065
    The starting material is obtained z.

   B. as follows: 6.5 parts by weight of 1-keto-2-methyl-7-benzy loxy -1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester are left with a Grignard solution from 0.6 parts by weight of magnesium and 2 parts by volume of ethyl bromide, react,

       heats 6 parts by weight of the carbinol obtained in this way with 25 parts by volume of formic acid on a water bath for the purpose of dehydration and saponifies the methyl carboxylate group by heating 5 parts by weight of dehydration product (1- ethylidene .. 2-methyl-7-benzyloxy-1,2,3 4-tetra- hydro-phenanthrene-2-carboxylic acid methyl ester)

         in a mixture of 10 parts by weight of potassium hydroxide, 7.5 parts by volume of water and 15 parts by volume of alcohol to 1600.
