Description

  

  Verfahren zur Darstellung eines in     2-Stellung    substituierten     Imidazoldihydrids-(4,6).            Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur Darstellung     eines    in       2-Stellung    substituierten     Imidazoldihydrids-          (4,5),    welches dadurch gekennzeichnet ist,  dass man einen     p-Methyl-phenylacetimino-          äther    mit     Äthylendiamin    umsetzt.  



  Das so gewonnene     2-(4'-Methyl-benzyl)-          imidazol-dihydrid-(4,5)        bildet    farblose Kri  stalle. Sein Hydrochlorid ist ein farbloses  Kristallpulver vom F. 206 bis 207  .  



  Die neue Verbindung     kann    als Arznei  mittel verwendet werden.    <I>Beispiel:</I>  2,3 Teile     p-Methyl-phenyl-acetiminoäthyl-          äther-hydrochlorid    der Formel  
EMI0001.0017     
    (hergestellt aus     p-Methyl-phenyl-acetonitril),     aus dem sich während der Umsetzung     p-Me-          thyl-phenylacetiminoäthyläther    bildet, wer-    den in 15 Teilen absolutem Alkohol gelöst.       Man    fügt ziemlich rasch 1 Teil Äthylen  diamin     hinzu,    erhitzt langsam auf<B>100'</B>     und     hält einige Stunden bei dieser Temperatur.

    Hernach vertreibt man den Alkohol, versetzt  den Rückstand mit verdünnter Natronlauge  und extrahiert erschöpfend mit Benzol. Nach  dem Trocknen über Pottasche wird das 2-(4'  Methyl-benzyl)-imidazol-dihydrid-(4,5) der  Formel  
EMI0001.0024     
         in    sein Hydrochlorid übergeführt.  



  An Stelle von     p-Methyl-phenylacetimino-          ä-thyläther    kann ebensogut ein anderer Äther,  wie z. B. der     Methyl-,        Propyl-    oder     Butyl-          äther        Verwendung        finden.     



  Statt vom salzsauren Salz des     p-Methyl-          phenylacetiminoäthers        kann    man auch von  einem andern Salze, wie z. B. vom     bromwas-          serstoffsauren,    vom schwefelsauren oder vom       methylschwefelsauren    Salz ausgehen.



  Process for the preparation of a 2-substituted imidazole dihydride (4,6). The subject of the present patent is a process for the preparation of an imidazole dihydride (4,5) substituted in the 2-position, which is characterized in that a p-methylphenylacetimino ether is reacted with ethylenediamine.



  The 2- (4'-methyl-benzyl) - imidazole-dihydride- (4,5) obtained in this way forms colorless crystals. Its hydrochloride is a colorless crystal powder from F. 206 to 207.



  The new compound can be used as a medicine. <I> Example: </I> 2.3 parts of p-methyl-phenyl-acetiminoethyl ether hydrochloride of the formula
EMI0001.0017
    (made from p-methyl-phenyl-acetonitrile), from which p-methyl-phenylacetiminoethyl ether is formed during the reaction, are dissolved in 15 parts of absolute alcohol. 1 part of ethylene diamine is added fairly quickly, heated slowly to <B> 100 '</B> and held at this temperature for a few hours.

    The alcohol is then driven off, the residue is mixed with dilute sodium hydroxide solution and extracted exhaustively with benzene. After drying over potash, the 2- (4 'methyl-benzyl) -imidazole-dihydride- (4,5) of the formula
EMI0001.0024
         converted into its hydrochloride.



  Instead of p-methyl-phenylacetimino-ethyl ether, another ether, such as e.g. B. the methyl, propyl or butyl ethers are used.



  Instead of the hydrochloric acid salt of p-methylphenylacetiminoäthers one can also use another salt, such as. B. start with the hydrobromic acid, the sulfuric acid or the methylsulfuric acid salt.
