  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a pure oxyhydrophenanthrene derivative can be obtained if 1-ethyl-2-methyl 7-oxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-ca: Carbonic acid treated with an esterifying agent which converts the hydroxyl group in the 7-position into the aoatoxy group.



       The not yet known end product of the process, the 1-ethyl-2-methyl-7-acetoxy 1,2,3,4,9,10-hexahydmo-phenanthrene-2-carboxylic acid, shows both parenteral and with oral application an extraordinarily high estrogenic effect. It should be used therapeutically or as an intermediate:

  used for the production of therapeutically usable compounds.



  For the conversion of the hydroxyl group in .. 7-position in the acetoxy group you use acetic acid or its derivatives, such as. B. acetic anhydride or acetyl chloride. Before working in the presence of condensing agents and / or catalysts.



  The starting material is z. B. obtained from the 7-methoxy-1-keto-2-methyl-1,2,3,4,9,10 hexahydro-phenantliren-2-ea.rbo @ nsäureme @ thyl- es.ter by Grignardation with an ethyl - magnesiu, mhalogenid., Isolation of the 1-ethylidene compound formed, hydrogenation of the ethylidene double bond and saponification of the 2-carboxylic acid ethyl ester and the 7-methoxy group. <I> example:

  1 part by weight of 1-ethyl-2-methyl-7-oxy 1,2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid of the formula
EMI0001.0061
    it is heated in a mixture of 10 parts by volume of pyridine and 5 parts by volume of acetic anhydride for 4-5 hours on a water bath.

   After cooling, water is added, shaken out with ether and the ether is washed with hydrochloric acid, bicarbonate solution and water.

   The residue of the evaporated ether solution gives, after recrystallization from dilute alcohol, the estrogenically active 1-ethyl-2-methyl-7-acetoxy-1,2, Ä, 4,9,10-hexahydro- phenanthrene-2 -arboxylic acid of the formula
EMI0001.0093
    The starting material is obtained z.

   B. as follows: 6.5 parts by weight of 1-keto-2-methyl-7-methoxy-1,2,3,4,9,10-hexahydro-phenanthrene-2-carbonsäumemethylester left with a Grignard solution prepared from 0.6 part by weight of magnesium and 2 parts by volume of ethyl iodide, react, isolate the 1,4-ethylidene-2-methyl-7-methoxy -1,2,3,4,9,10-hexahydro- phenanthrene-2-carboxylic acid methyl ester, r, from F.

   146-147, hydrogenated 4 parts by weight of it in the presence of 4 parts by weight of a nickel catalyst and 100 parts by volume of A.1 alcohol and saponified the methyl carboxylate and methoxy group by heating 5 parts by weight of the hydrogenation product (1-ethyl - 2'-methyl-7-methoxy-1,2,3,4,9,10-hexahydro:

          phenanthrene-2-carbonic acid methyl ester) in a mixture of 25 parts by weight of potassium hydroxide and 50 parts by volume of alcohol in the inclusion, more to 190 to 210, with the 1-ethyl-2-m @ ethyl-7-oxy 1 , 2,3,4,9,10-hexahydro-phenanthrene-2-carboxylic acid of mp 184-186 is formed.
