  Process for the preparation of a new oxyhydrophenanthrene derivative. It has been found that a new Oxyhydrophenanthren-Denivat can gelan conditions if the 1-ethyl-2-methyl- 7 - oxy - 1,2,3,4 - tetrahydro - phenanthrene - 2 - carbonsäurem @ ethyl ester with a esterify the remedy,

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



  The as yet unknown end product of the process, the 1-ethyl-2-methyl-7-benzoyl oxy-1,2,3,4-t.etraIlydro-phenanthrene-2-earbonic acid methyl ester of F. 1-0-132 shows an extraordinarily high estrogenic effect in both parenteral and oral administration. It should find therapeutic use or serve as an intermediate for the preparation of therapeutically useful compounds.



  Benzoic acid or its derivatives are used to convert the hydroxyl group in the 7-position into the benzoyloxy group. such as B. benzoyl 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 tetrahydno-phenanthrene-2-ca.rboxylic acid methyl ester by Grignardation with an ethyl magnesium halide, elimination of water from the 1 -Ethyl-l-oxy-2-methyl'-7- methoxy, -1,2,3,4 - testrahydro - phenanthrene - 2-methyl ester,

          Hydrogenation of the double bond formed and subsequent cleavage of the 7-methoxy groups with formation of 1-ethyl-2-methyl'-7-oxy-1,2,3,4 t: etrahydTo-phenanthrene-2; methyl esters., <I> Example:

  </I> 1 part by weight of 1-ethyl-2-methyl-7-oxy-1,2,4-tetra.hydro-phenanthrene-2-carboxylic acid methyl ester of the formula
EMI0001.0068
    is m a mixture of 10 parts by volume of pyridine and 5 parts by volume of benzoyl chloride for 24 hours. Let stand room temperature.

   Then water is added, extracted with ether and the ether washed with hydrochloric acid, bicarbonate solution and water. The residue of the evaporated ether solution gives, after recrystallization from alcohol, the estrogenically active 1-ethyl-2-methyl-7-benzoyloxy -1,2,3,4 tetrahydro-phenanthrene-2-carboxylic acid methyl ester of F.

       1-0-132 and the formula
EMI0001.0092
      The starting material is obtained z. $. as follows: 12 parts by weight of 1-geto-2-methyl-7-merthoxy -1, 2, 3, 4-tetna.hydro-phenanthrene-2-carboxylic acid methyl ester are left with a Grignard solution prepared 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-1-oxy-2-methyl -1,2,3,4-tetrahydro-phenanthene-2-carboxylic acid methyl ester of F.

       153 for the purpose of dehydration in a solution of 0.3 part by weight of iodine in 40 parts by volume of chloro form and 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 form 1-ethyl-2-methyl-7-methoxy - 1,2,3,4 = letrahydro, -phenanthrene- 2- ca.

   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 hydrochloride.
