  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new oxyhydrophenanthrene derivative can gelan gene if you have a 1-ethyl-2-methyl- 7 - methoxy -1, 2, 3, 4,9,10 - hexahydro - phen- anthrene, the in the 2-position one by Hy drolysis in the free carboxyl group on feasible substituents, z.

   B. contains an esterified canboxyl group, treated with hydrolyzing agents to form a free carboxyl group.



  The not yet known end product of the process, the 1-ethyl-2-m-ethyl-7-metho @ xy 1,2,3,4,9,10-hexahydro-phenanthtr-n-2-carbo.n-acid vom F. 168-170, shows an extraordinarily high estrogenic effect on both parenteral and oral administration. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically usable 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-1,2,3,4,9,10-hexahy4ro-phenanthrenes which have a substituent in the 2-position which can be converted into the free carboxyl group by hydrolysis , by Grignardation with an ethyl magnesium halide, isolation of 1-ethylidene-2-methyl-7-methoxy-1,2,3,4,9,

  10-hexahydro-phenanthrene derivative. and subsequent hydrogenation of the double bond formed. <I> Example: </I> 3.3 parts by weight of 1-ethyl-2-methyl'-7 methoxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid methyl ester of mp 77-79 and the formula
EMI0001.0058
    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, the potassium salt of the carboxylic acid crystallizes out in the warmth. This is taken up in 100 parts by volume of water, whereupon the sparingly soluble galium salt precipitates in shiny platelets after a short time.

       By decomposing it with dilute hydrochloric acid, the estrogenically active 1-ethyl-2-methyl-7-methoxy -1,2,3,4,9,10-hexahydro- phenanthrene-2-carboxylic acid of the formula is obtained
EMI0001.0081
    obtained, which melts after Umlöscn from acetone at 168-170. The starting material is obtained z.

   B. as follows: 8.9 parts by weight of 1-geto-2-methyl-7-m-ethoxy-1, 2, 3, 4, 9, 10-hexahydro-phenanthrene-2-carboxylic acid methyl ester are left with a Grign.ard Solution, made from 1.08 parts by weight of magnesium and 6.95 parts by weight of ethyl iodide, react, isolates the 1-ethylidene-2-methyl-1,2,3,4,9,10 hexahydro-phenanthrene- 2-carbons @ acid methyl ester from F.

       146-147 and hydrogenated. 1 weight of the ethylidene compound in 30 parts by volume of alcohol in the presence of 0.1 part by weight of a platinum catalyst to give 1-ethyl-2-methyl-7-methoxy-1,2,3,4,9,10 hexahydro-phenanthrene -2-carbons, acid methyl, esters of F. 77-79.
