  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new ogyhydrojhenanthrene derivative can be obtained if a 1-ethylidene-2-methyl-7-methogy-1,2,3,4,9,

  10 - hexahydro- phenanthrene-2-carboxylic acid treated with hydrogenating agents for the purpose of converting the ethylidene group into an ethyl radical.



  Catalytic hydrogenation, for example, can be used to convert the ethylidene group into the ethyl radical.



  The as yet unknown end product of the process, the 1-ethyl-2-methyl-7-methoxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid from F.

   168-170, shows an extraordinarily high estrogenic effect both on parenteral and on oral administration. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically usable compounds.



  <I> Example: </I> 3 parts by weight of 1-ethylidene-2-methyl-7-methoxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid with a melting point of 191-193 of the formula

   146-147 and subsequent saponification with potassium hydrogen at 160) is shaken at 50 in a solution of 125 parts by volume of water and 4 parts by weight of sodium hydrogen with 2.5 parts by weight of a nickel catalyst under hydrogen. After the amount of hydrogen calculated for 1 molar equivalent has been taken up, the catalyst is filtered off and the filtrate is acidified with mineral acid.

    One takes up in ether, the ether solution is dried and evaporated. The estrogenically active 1-ethyl-2-methyl-7-methoxy 1,2,3,4,9,10-hegahydro-phenanthrene-2-carbon is obtained by recrystallizing the residue from an acetone-methyl alcohol mixture - acid of the formula
EMI0001.0079
         in the form of colorless crystals from F.

   168 to 170 together with a small amount of an ineffective diastereoisomer of F. 171 to 173.
