  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new oxyhydrophenanthrene derivative can be obtained if the 1-ethyl-2-methyl-7-oxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester is esterified treated the means

   which converts the hydroxyl group in the 7-position into the propionyloxy group.



  The not yet known end product of the process, the 1-ethyl-2-methyl-7-pro, -pionyloxy -1,2,3,4-tetmhydToi-phenanthrene-2-carboxylic acid methyl ester of F. 89-90, shows both at An extraordinarily high estrogenic effect, both pa.renteral and oral administration. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically useful compounds.



  For the conversion of the hydroxyl group in the 7-position in the Prepionyloxygi-uppe ver used propionic acid or its derivatives, such as. 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 1-keto-2-methyl-7-methoxy-1,2,3,4 tetrahydro-phenanthrene-2-carbon, acid methyl ester by Grignardation with an ethyl - magnesium halide, dehydration from the 1-ethyl-1-oxy-2-methyl-7-methoxy-1,2, 4-tetrahydro-phenanthrene-2-carbonic acid methyl ester obtained in this way, hydrogenation of the methyl esters formed,

       Double bond and subsequent cleavage of the 7-methoxy group with formation of 1 Athy1-2-methyl-7-oxy-1,2,3,4 = tetrahydro-phenanthrene-2-carboxylic acid methyl ester.



  <I> Example: </I> 1 part by weight of 1 equivalent ethyl-2-methyl-7-oxy-1,2,3,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester of the formula
EMI0001.0066
         it is heated in a mixture of 10 parts by volume of pyridine and 5 parts by volume of propionic anhydride on a water bath for 4-5 hours.

   After cooling, water is added, shaken out with ether and the ether with hydrochloric acid. Bi carbonate solution and water washed. The residue of the evaporated ethene solution delivers, after crystallization from methanol, the estrogenically active 1-ethyl - 2 - methyl - 7 propionylo @ xy-1,2,3,4-tetrahydro-phenanthrene- 2 = canbon, acid methyl ester of F. 89- 90 of the formula
EMI0001.0082
      The starting material is obtained z.

   B. as follows: 12 parts by weight of 1-K @ eto-2-methyl-7-methoxy -1,2, 3,4-tetrahydro- phenanthrene-2 carboxylic acid methyl ester is left with a Grignard solution, inhibited from 1.25 parts by weight of magnesium and 5 parts by volume of ethyl bromide, react, boils 8 parts by weight of the,

      1-ethyl-l-oxy-2-methyl -1,2,8,4-tetrahydro-phenanthrene-2-carboxylic acid methyl ester obtained in this way from F.

   158 for the purpose of dehydration in a solution of 0.8 part by weight of iodine in 40 parts by volume of chloro form, hydrogenated 1 part by weight of the ethylidene compound in 30 parts by volume of alcohol in the presence of 1 part by weight of a nickel catalyst to give 1-ethyl-2-methyl-7-meth oxy-1,2,3,4-tetrahydno-phenanthrene-2-carboxylic acid methyl ester from F.

   76-78 and then cleaves the 7-methoxy group by briefly heating 1 part by weight of the latter compound with 10 parts by weight of pyridine hydnochloride.
