Description

  

      Verfahren        zur    Herstellung neuer     Oxyäthyl-diphenyl-methyl-piperidine       Gegenstand der Erfindung ist die Herstellung von       1-(ss-Oxy-äthyl)-2-diphenylmethyl-piperidinen.    Die  Verbindungen können auch substituiert sein, insbe  sondere können die     Phenylreste    eine oder mehrere  niedere     Alkyl-    oder     Alkoxygruppen    oder Halogen  atome enthalten.  



  Die genannten Verbindungen weisen eine starke  zentralerregende Wirkung mit     Motilitätssteigerung     auf. Sie können als Heilmittel, insbesondere als     Sti-          mulantien,    oder als Zwischenprodukte     zu    deren Her  stellung verwendet werden. Besondere Bedeutung be  sitzen das     1-(ss-Oxy-äthyl)-2-diphenylmethyl-piperidin     und seine     Salze.     



  Das erfindungsgemässe     Verfahren    zur Herstellung  der neuen     1-Oxyäthyl-2-diphenylmethyl-piperidine    ist  dadurch     gekennzeichnet,    dass man     gegebenenfalls    sub  stituierte     2-Diphenylmethyl-piperidine    mit Äthylen  oxyd behandelt.  



  Je nach der Arbeitsweise erhält man die neuen  Verbindungen in Form     ihrer    Basen oder     Salze.    Aus  den     Salzen    können in an sich bekannter Weise die  freien     Piperidinbasen    gewonnen werden.

   Von letzte  ren wiederum lassen sich durch     Umsetzung    mit Säu  ren, die zur Bildung therapeutisch verwendbarer     Salze          geeignet    sind, Salze gewinnen, wie zum Beispiel der       Halogenwasserstoffsäuren,    Schwefelsäure, Salpeter  säure, Phosphorsäure, Essigsäure,     Propionsäure,          Oxalsäure,        Äpfelsäure,    Zitronensäure,     Methansulfon-          säure,        Äthansulfonsäure,        Oxyäthansulfonsäure,        Ben-          zoesäure,

          Salicylsäure,        p-Amino-salicylsäure    oder     To-          luolsulfonsäure.     



  In den nachstehenden Beispielen sind die Tem  peraturen in Celsiusgraden angegeben.  



  <I>Beispiel 1</I>  75 g     2-Diphenylmethyl-piperidin    werden in l50     em3     Alkohol gelöst und 25g     Athylenoxyd    während 24    Stunden bei 20  einwirken gelassen. Das     1-(f        Oxy-          äthyl)-2-diphenylmethyl-piperidin        schmilzt    bei 106  bis 107  und siedet bei 180-181  (0,1     mm);    sein  Hydrochlorid     besitzt    einen F. von 166-167 ; die  Ausbeute ist quantitativ.  



  <I>Beispiel 2</I>  Analog Beispiel 1 werden 10 g     2-(Phenyl-p-clüor-          phenylmethyl)-piperidin    mit 3 g     Äthylenoxyd    in  50     cm3        Alkohol        umgesetzt.    Man erhält     1-(fl'-Oxy-          äthyl)    - 2-     (phenyl-p-chlor-phenylmethyl)        -piperidin;          I-p-        0.0s    =     184-187 ;    Ausbeute 11,5 g.



      Process for the production of new oxyethyl-diphenyl-methyl-piperidines The invention relates to the production of 1- (β-oxy-ethyl) -2-diphenylmethyl-piperidines. The compounds can also be substituted, in particular the phenyl radicals can contain one or more lower alkyl or alkoxy groups or halogen atoms.



  The compounds mentioned have a strong central stimulating effect with increased motility. They can be used as remedies, in particular as stimulants, or as intermediates for their manufacture. 1- (ss-oxy-ethyl) -2-diphenylmethyl-piperidine and its salts are of particular importance.



  The process according to the invention for the preparation of the new 1-oxyethyl-2-diphenylmethyl-piperidines is characterized in that optionally substituted 2-diphenylmethyl-piperidines are treated with ethylene oxide.



  Depending on the procedure, the new compounds are obtained in the form of their bases or salts. The free piperidine bases can be obtained from the salts in a manner known per se.

   From the latter, in turn, salts can be obtained by reacting them with acids that are suitable for forming therapeutically useful salts, such as hydrohalic acids, sulfuric acid, nitric acid, phosphoric acid, acetic acid, propionic acid, oxalic acid, malic acid, citric acid, methanesulfonic acid , Ethanesulfonic acid, oxyethanesulfonic acid, benzoic acid,

          Salicylic acid, p-amino-salicylic acid or toluenesulphonic acid.



  In the examples below, the temperatures are given in degrees Celsius.



  <I> Example 1 </I> 75 g of 2-diphenylmethyl-piperidine are dissolved in 150 cubic meters of alcohol and 25 g of ethylene oxide are allowed to act at 20 for 24 hours. The 1- (f oxyethyl) -2-diphenylmethyl-piperidine melts at 106 to 107 and boils at 180-181 (0.1 mm); its hydrochloride has an F. of 166-167; the yield is quantitative.



  <I> Example 2 </I> Analogously to example 1, 10 g of 2- (phenyl-p-chlorophenylmethyl) piperidine are reacted with 3 g of ethylene oxide in 50 cm3 of alcohol. 1- (fl'-oxyethyl) - 2- (phenyl-p-chlorophenylmethyl) piperidine is obtained; I-p-0.0s = 184-187; Yield 11.5g.
