  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new oxyhydrophenanthrene derivative can be obtained if 1-ethyl-2-methyl 7-oxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid is used treated with an esterifying agent which converts the 1-lyd, noxyl group in the 7-position into the propionyloxy group.



  The as yet unknown end product of the process, the 1-ethyl-2-methyl-7-propionyloxy-1,2,3,4,9,10-hexahydro-phen-anthrene-2-carboxylic acid, shows both par enteraler as well as an extremely high estrogenic effect when administered orally. It should find therapeutic use or serve as an intermediate product for the production of therapeutic compounds, s @ ch usable.



  To convert the hydroxyl group in the 7-position into the propionyloxy group, propionic acid or its derivatives are used. how. z. B. propionic anhydride or propionyl chloride. It is advantageous to work in the presence of condensing agents and / or catalysts.



  The starting material is z. B. obtained from the 7-methoxy-l-keto-2-methyl-1,2,3,4,9,10 hexahydro-phenanthrene-2-carboxylic acid methyl ester by guignardation with an ethyl magvesium.halide,

      Isolation of the 1-ethylidene compound formed hydrogenation of the ethylidene double bond and saponification of the methyl 2-carboxylate and the 7-1 ethoxy group. Example:

       1 part by weight of 1-ethyl-2-methyl-7-oxy 1., 2,3,4,9,10-hexahydro-phenanthrene-2-earzbo # n-acid of the formula

    it is heated in a mixture of 10 parts by volume of pyridine and 5 parts by volume of propionic anhydnide on the water bath for 4-5 hours. After cooling, water is added,

   shaken out with ether and the ether washed with hydrochloric acid, bicarbonate solution and water. The residue of the evaporated ether solution delivers, after crystallization from dilute alcohol, the estrogenically active 1-ethyl-2-methyl-7-propionyloxy -1,2,3,4,9,

   isolates the 1-ethylidene-2-methyl-7-methoxy-1,2,3,4,9,10-hexahydro- phenanthrene-2-carboxylic acid methyl ester of melting point 146-147, hydrogenated 4 parts by weight of it in the presence of 4 parts by weight of one Nickel catalyst and 100 parts by volume of all:

  oUol and saponified the carboxylic acid methyl ester and the 14lethoxy group by heating 5 parts by weight of the.

       Hydrogenation products (1-ethyl - 2 - methyl - 7 - methoxy 1,2,3,4,9,10-hexahydro-phenauthrene-2-carboxylic acid methyl ester) in a mixture of 25 parts by weight of galium hydroxide and 50 vol. Divide the alcohol in the containment tube to 190 to 210, with the 1-ethyl-2-methyl-7-o @ xy-1,2,3,4,9,
