  Process for the preparation of a new oxy-oetahydrophenanthrene derivative. It has been found that a new oxy-octahydrophenanthrene derivative can be obtained by using a 1-ethyl-2-ethyl-1,2,3,4,9,10,11,12-octahydro-phenanthrene - 2 -ca.rbonsä.ure, which has a substituent in the 7-position which can be converted into the hydroxyl group by hydrolysis, e.g. B.

    an etherified or esterified hydroxyl such as an alhoxy or acyloxy group, contains., Treated for the purpose of forming a free hydroxyl group with hydrolyzing agents.



  Not that yet. known end product of the process, the 1-ethyl-2-methyl-7-oxy-1,2, 3,4,9,1.0,11,12-octahydro- phenanthrene -21-carboxylic acid with a melting point of 181 to 182, shows an extraordinarily high oestrogenic - # Virlzi-ng with parenteral as well as with oral application. It should find therapeutic use or serve as an intermediate product for the production of therapeutically usable compounds.



  For the hydrolysis of the substituent in the 7-position one uses, for example, inorganic bases, such as alkali: - or Erd- <illzalihy droxyde, mixtures of organic and inorganic acids, such as acetic acid-hydrochloric acid or acetic acid-hydrobromic acid, or salts of organic bases with inorganic acids such as pyridine hydrochloride.



  The starting materials are obtained, for example, from 1-keto-2-methyl-1,2,3,4,9,10, 11,12-octahydro-phenanthrene-2-carboxylic acid esters which are in the 7-position by hydro lysis into the hydroxyl group convertible substituents contain by Grignardization with an ethylmagnesium halide, elimination of water from the Ca.rbinol obtained,

          Saponification of the esterified carboxyl group and hydrogenation of the ethylene double bond.

    heated with 10 parts by weight of pyridine hydrochloride for 3 to 4 hours to 170 M180. After cooling, water is added, shaken out with ether and the ether is washed with hydrochloric acid, biocarbonate solution and water.

   The residue of the evaporated ether solution gives, after recrystallization from ethyl acetate, the estrogenically active 1-ethyl-2-methyl-7-oxy-1,2,3,4, 9,10,11,121-octahydro-phenanthrene; 2-carboxylic acid with a melting point of 181 to 182 of the formula

      6.5 parts by weight of 1-keto-2-methyl-7-methoxy-1,2,3,4,9,10,11,12-octa-hydro-phenanthrene-2-carboxylic acid methyl ester from F.

   133 to 135 are left out with a Grignard solution. 0.6 part by weight of magnesium and 2 parts by volume of ethyl bromide, react, 6 parts by weight of the carbinol obtained in this way are heated for the purpose of splitting off water in a mixture of 6 parts by volume of phosphorus oxychloride and 60 parts by volume of pyridine,

       the methyl carboxylate group is saponified by heating 5 parts by weight of water splitting product (1-ethylidene - 2-methyl-7-methoxy-1,2,3,4,9,10,11,12 .-, octahydro- phenanthrene - 2 - methyl carboxylate) in a mixture of 10 parts by weight of potassium hydroxide, 7,
