Description

  

  Procédé de préparation     d'un    nouveau dérivé de la     phénothiazine.       La présente invention a pour objet un  procédé de préparation d'un nouveau dérivé  de la     phénothiazine,    la     chloro-3-(diméthyl-          amino-3'-propyl)-10-phénothia.zine    répondant  à la formule:  
EMI0001.0006     
    Le procédé selon la présente invention     est     caractérisé en ce que l'on fait réagir la     di-          méthylamine    sur une     chloro-3-(halogéno-3,'-          propyl)        -10-phénothiazine.     



  La réaction de la     diméthylamine    sur la       chloro-3-        (halogéno-3'-propyl)        -10-phénothiazine     est avantageusement réalisée en autoclave, de  préférence à une température de 100-150 .  On peut également opérer à température ordi  naire, mais la réaction est beaucoup     phis     lente. On peut travailler avec ou sans solvant,  mais il est préférable d'utiliser un solvant du  groupe des alcools aliphatiques ou mieux des  carbures aromatiques.  



  La     chloro-3-(diméthylamino-3'-propyl)-10-          phénothiazine    obtenue par le procédé de l'in  vention est une nouvelle substance dont le  chlorhydrate fond à 177-178  C. Elle possède  des propriétés physiologiques précieuses, qui  permettent de l'utiliser comme antihistamini-    que,     ganglioplégique,    spasmolytique, anesthé  sique local, analgésique, sympatholytique,  antifungique.     Enfin,    elle s'est révélée particu  lièrement intéressante     comme        potentialisateur     des anesthésiques généraux, des analgésiques  et des anesthésiques locaux.

      <I>Exemple:</I>  On mélange 31 g de     cbloro-3-        (cblor        o-3'-          propyl)-10-phénothiazine    brute avec 50     em3     de solution alcoolique de     diméthylamine    à  30     1/o    et on chauffe le tout en tube scellé pen  dant 7     heures    à 120 . On     chasse    ensuite l'al  cool et     l'excès    de     diméthylamine,    reprend par  l'eau     acidulée    et filtre. On alcalinise à la  soude et     extrait    à l'éther.

   On chasse l'éther et  rectifie; on obtient la     chloro-3-(diméthyl-          amino    -     3'-        propyl)    -10 -     phénothiazine        Eb.    0,8  = 200-210 , dont le chlorhydrate fond à  177-178 , le picrate de     couleur    rouge à 169   et le     méthylsulfométhylate    à 140-141 . La       chloro-3-        (chloro-3'-propyl)-10-phénothiazine     a été préparée par analogie avec la méthode  décrite par     Gilman    et Shirley Am.

   Soc. 66  890 (1944), par action du     p-toluène-sulfonate     de     y-chloropropyle    sur la     chlorophénothiazine     lithique.



  Process for the preparation of a novel derivative of phenothiazine. The present invention relates to a process for preparing a novel derivative of phenothiazine, chloro-3- (dimethyl-amino-3'-propyl) -10-phenothia.zine corresponding to the formula:
EMI0001.0006
    The process according to the present invention is characterized in that the dimethylamine is reacted with a chloro-3- (halogeno-3, '- propyl) -10-phenothiazine.



  The reaction of dimethylamine with chloro-3- (halogeno-3'-propyl) -10-phenothiazine is advantageously carried out in an autoclave, preferably at a temperature of 100-150. It is also possible to operate at ordinary temperature, but the reaction is very slow. It is possible to work with or without a solvent, but it is preferable to use a solvent from the group of aliphatic alcohols or better still of aromatic carbides.



  Chloro-3- (dimethylamino-3'-propyl) -10-phenothiazine obtained by the process of the invention is a new substance whose hydrochloride melts at 177-178 C. It has valuable physiological properties, which make it possible to use it as an antihistamine, ganglioplegic, spasmolytic, local anesthesia, analgesic, sympatholytic, antifungal. Finally, it has proved to be particularly interesting as a potentiator of general anesthetics, analgesics and local anesthetics.

      <I> Example: </I> 31 g of crude cbloro-3- (cblor o-3'-propyl) -10-phenothiazine are mixed with 50 em3 of alcoholic solution of dimethylamine at 30 1 / o and the whole is heated in sealed tube for 7 hours at 120. The alcohol is then removed and the excess of dimethylamine, taken up in acidulated water and filtered. It is basified with sodium hydroxide and extracted with ether.

   The ether is driven out and rectified; chloro-3- (dimethylamino - 3'-propyl) -10 - phenothiazine Eb. 0.8 = 200-210, of which the hydrochloride melts at 177-178, the red colored picrate at 169 and the methylsulfomethoxide at 140-141. Chloro-3- (chloro-3'-propyl) -10-phenothiazine was prepared by analogy with the method described by Gilman and Shirley Am.

   Soc. 66890 (1944), by the action of γ-chloropropyl p-toluenesulphonate on lithic chlorophenothiazine.
