  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-ethyl-2-methyl-7-oxy-1,2,3,4-tetrahydro -phenanthTen, the. In the 2-position a substituent which can be converted into the free carboxyl group by hydrolysis, e.g.

       B., contains an esterified carboxyl group, treated with hydrolyzing Alit.teln in order to form a f, roien carboxyl group.



       The not yet known end product of the process, the 1- ethyl - \? - methyl - 7 - oxy - 1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid from F. 204, shows an extraordinarily high estrogenic effect both pacenteral and oral administration. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically applicable compounds.



  For the conversion of 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-methyl-7-methoxy-1,2,3,4-tetra liydro-phenanthrenes which have a substituent which can be converted into the free carboxyl group by hydrolysis in the 2-position, by Grignardation with a Ethylmagnesium halide,

          Elimination of water from the carbinol, which is so held up. Hydrogenation of the double bond formed and subsequent hydrolysis of the methoxy group in the 7-position. Example:

       3.3 parts by weight of 1-ethyl-2-methyl-7-oxy-1, 2, 3,4-tetrahydro-phenanthrene-2-caxtbonic acid methyl ester of F. 117 of the formula
EMI0001.0056
    are heated to 160 in a mixture of 16.5 parts by weight of potassium hydroxide, 5 parts by volume of water and 10 parts by volume of alcohol. After the alcohol has evaporated, it still crystallizes in the warmth.

       Potassium salt of the oxyacid from .. This is taken up in 100 vol. Parts of water and obtained from it by etching with dilute hydrochloric acid the estrogenic 1-ethyl-2-methyl-7-oxy-1, 2,3,4-tetrahydr, o-phenanthrene-2-, carboxylic acid d ex formula
EMI0001.0073
    which melts at 204 after dissolving from ethyl acetate.



  The starting material is obtained z. B. as follows: 12 parts by weight of 1-keto-2-methyl-7-methoxy -1, 2, 3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester are left with a G:

  iignard solution, made from 1.25 parts by weight of magnesium and 5 parts by volume of ethyl chloride, reacts, boiling 8 parts of the 1-ethyl-1-oxy-2-m @ ethyl -1,2 obtained in this way , 3,4 - tetrahydro - phenanthrene - 2 - carboxylic acid methyl ester from F.

   153 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, hydrates 1 part by weight of the ethylidene compound in 30 parts by volume of alcohol to 1-ethyl -'-) - methyl-7-methoxy-1,2 , 3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester from F.

   76-78 and then hydrolyzes the 7-methoxy group by treatment with a mixture of glacial acetic acid and hydrochloric acid.
