  "Procédé de préparation d'un nouvel ester de 3-méthoxyoestradiol et produit obtenu". 



   La présente invention concerne un nouvel ester de 3-méthoxyoestradiol et un procédé de préparation de celui-ci. 



   Le composé visé pax l'invention est l'ester de l'acide 1-adamantoïque et du 3-méthoxyoestradiol. 

 <Desc/Clms Page number 2> 

 



   L'invention vise également un procédé de préparation d'unéster de 3-méthoxyoestradiol consistant à faire réagir le 
 EMI2.1 
 3-méthoxyoestradiol avec l'anhydride de l'acide 1-adamantolque, un anhydride mixte de l'acide 1-adaman.toqueet de l'acide trzfluoroacétique, ou un chlorure d'acide 1-adamantoique, en présence de pyridine comme catalyseur, pour former l'ester 1-adamantolque du 3-méthoxyoestradiol. 



   On utilise de préférence un solvent inerte comme milieu de dispersion. 
 EMI2.2 
 



  Le 5-méthoxyoestradiol¯17p-(l-adamantoate) , qui est le composé obtenu par le procédé objet de l'invention, est un produit solide cristallin blanc, soluble dans la plupart des solvants organiques. Ce nouveau composé est avantageux comme anti-androgène pour un certain nombre de mammifères, car il comoat es effets physiologiques des hormones mâles. Contraire- ment au 3-méthoxyoestradiol, qui est un inhibiteur général de la gonadotrophine, le   3-méthoxyoestradiol-17p-(l-adamantoate)   est un anti-androgène spécifique. 



   On donne l'exemple non limitatif suivant à titre . d'illustration de l'invention. 



    EXEMPLE.   
 EMI2.3 
 



  3-méthoxyoestradiol-120-(l-adamantoate) 
On dissout 800 mg de 3-méthoxyoestradiol dasn 50   cm   de benzène anhydre. On ajoute 662 mg de chlorure d'acide   adaman-   toïque dissous dans 5 cm de benzène, puis 0,04 cm de pyridine. 



  On chauffe le mélange réactionnel à la température de reflux pendant 2 heures environ et on le verse dans une solution aqueuse à 2% de bicarbonate de sodium maintenue à 0 C environ. 



  On extrait le mélange résultant avec de l'éther, on sépare l'extrait éthéré et on le sèche. En éliminant l'éther par 
 EMI2.4 
 évaporation'sous vide, on obtient le 3-méthoxyoestradiol-17P- 

 <Desc/Clms Page number 3> 

 (1-adamantoate) comme résidu. La recristallisation de celui-ci dans l'éther donne le 3-méthoxyoesradilol-178-(1-admanatoae), fondant à 210-212 C. 



  Analyse : Calculé : C= 80,31 ;H= 8,99. 



  Trouvé :C= 80,57 ; H= 9,07. 



   REVENDICATIONS. 



   1. Le   3-méthoxyoestradiol-17-(1-adamantoate).   



   2. Procédé de préparation d'un ester de 3-méthoxy- oestradiol, caractérisé en ce qu'on fait réagir le 3-méthoxy- oestradiol avec l'anhydride de l'acide 1-adamantoïque, un an- hydride mixte de l'acide 1-amonatoïque, et de l'acide trifluoro- acétique, ou le chlorure de l'adcie 1-amdahotïqaue en présence de pyridine comme catalyseur, pour former l'ester 1-adaman- rtoïqeu du 3-méthoxyoestradiol.

  "Process for the preparation of a novel 3-methoxyoestradiol ester and product obtained".



   The present invention relates to a novel 3-methoxyoestradiol ester and a process for the preparation thereof.



   The compound targeted by the invention is the ester of 1-adamantoic acid and 3-methoxyoestradiol.

 <Desc / Clms Page number 2>

 



   The invention also relates to a process for the preparation of an ester of 3-methoxyoestradiol consisting in reacting the
 EMI2.1
 3-methoxyoestradiol with 1-adamantoic acid anhydride, a mixed anhydride of 1-adaman.toque acid and trzfluoroacetic acid, or 1-adamantoic acid chloride, in the presence of pyridine as catalyst, to form the 1-adamantol ester of 3-methoxyoestradiol.



   Preferably, an inert solvent is used as the dispersing medium.
 EMI2.2
 



  5-Methoxyoestradiol¯17p- (1-adamantoate), which is the compound obtained by the process which is the subject of the invention, is a white crystalline solid product, soluble in most organic solvents. This new compound is advantageous as an antiandrogen for a number of mammals, since it coats the physiological effects of male hormones. Unlike 3-methoxyoestradiol, which is a general gonadotropin inhibitor, 3-methoxyoestradiol-17p- (1-adamantoate) is a specific antiandrogen.



   The following non-limiting example is given as a title. illustration of the invention.



    EXAMPLE.
 EMI2.3
 



  3-methoxyoestradiol-120- (l-adamantoate)
800 mg of 3-methoxyoestradiol are dissolved in 50 cm of anhydrous benzene. 662 mg of adamantoid acid chloride dissolved in 5 cm of benzene are added, followed by 0.04 cm of pyridine.



  The reaction mixture is heated at reflux temperature for about 2 hours and poured into a 2% aqueous solution of sodium bicarbonate maintained at about 0 ° C.



  The resulting mixture is extracted with ether, the ethereal extract is separated and dried. By eliminating the ether by
 EMI2.4
 evaporation under vacuum, we obtain 3-methoxyoestradiol-17P-

 <Desc / Clms Page number 3>

 (1-adamantoate) as a residue. Recrystallization of this from ether gives 3-methoxyoesradilol-178- (1-admanatoae), melting at 210-212 C.



  Analysis: Calculated: C = 80.31; H = 8.99.



  Found: C = 80.57; H, 9.07.



   CLAIMS.



   1. 3-Methoxyoestradiol-17- (1-adamantoate).



   2. Process for the preparation of an ester of 3-methoxy-estradiol, characterized in that the 3-methoxy-estradiol is reacted with the anhydride of 1-adamantoic acid, a mixed anhydride of the. 1-amonatoic acid, and trifluoroacetic acid, or 1-amdahotic acid chloride in the presence of pyridine as a catalyst, to form the 1-adamantoid ester of 3-methoxyoestradiol.
