  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new Oxyhydrophena.nthren derivative can be obtained if one. 1-ethyl-2-methyl-1,2, ä, 4-tetrahydro-ph enanthrene,

      that in the 7-position a substituent which can be converted into the hydroxyl group by hydiolysis and a substituent in the 2-position which can be converted into the carboxyl group by hydrolysis, e.g.

   B. in the 7-position contains an etherified or watered hydroxyl, such as an alkoxy or acyloxy group, and in the 2-position an esterified carboxyl group, for the purpose of simultaneous formation of a free hydroxyl and canboxyl group, with hydro- lysing agents treated.



  The as yet unknown end product of the process, the 1-ethyl-2-methyl-7-oxy-1,2,3,4-tetraIlydro-phenanthrene-2-carboxylic acid from F. 204, shows both in pa.renteral and in oral application has an extremely high estrogenic effect. It should find therapeutic use or serve as an intermediate product for the production of therapeutically usable compounds.



  For the simultaneous hydrolysis of the substituents in the 7- and 2-positions, for example, inorganic bases, such as alkali or alkaline earth metal hydroxides, are used in the inclusion tube, or salts of organic bases with organic acids, such as pyridine hydrochloride.



  The starting materials are z. B. obtained from 1-keto-2-methyl-1,2,3,4-tetrahydro-phenanthrenes, which have a through in the 7-position. Hydrolysis in the Hyduoxylgrup @ pe as well as a substituent in the 2-position which can be converted into the carboxyl group by hydrolysis, by Grignardation with an ethyl magnesium halide,

      Elimination of water from the carbinol obtained and hydrogenation of the ethylene double bond.



       Example: 1 part by weight of 1-ethyl-2-methyl-7-methoxy-1,2,3,4-tetrahydro-phenanthene-2-carboxylic acid methyl ester of M. 76-78 and the formula
EMI0001.0074
    it is heated with 5 parts by weight of potassium hydroxide and 10 parts by volume of methanol for 5 hours in a one: closing tube to 200-210. After cooling, water is added, acidified with hydrochloric acid, shaken out with ether and the ether washed with saturated bicarbonate 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-tet.rahydro- phenanthrene-2-carboxylic acid of F. 204 and the formula
EMI0002.0001
    The starting material is obtained z.

   B. as follows: 6.5 parts by weight of 1-geto-2-methyl-7-methoxy -1, 2,3,4 - tetrahydno - phenanthrene - 2-, carboxylic acid methyl ester is left with a Grignard solution made from 0, 6 parts by weight of magnesium and 2 parts by volume of ethyl, b.romide, reag-iemen,

          eiiwarms 6 parts by weight of the carbinol obtained in this way with a temperature of 153 to split off water with 25 parts by volume of formic acid on a water bath and hydrogenates 2 parts by weight of the 1-ethylidene-2-methyl-7-methoxy-1,2,3,4 teurahydro -phenanthrene-2-carboxylic acid-ethyl ester in 100 parts by volume of alcohol,

   in the presence of 2 parts by weight of one. Platinum catalyst to 1-ethyl-2-methyl-7-methoxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester of F. 76-78.
