Description

  

      Verfabren    zur Darstellung einer Doppelverbindung der     Pyridinreihe.       Es wurde gefunden, dass man zu einer  Doppelverbindung der     Pyridinreihe    gelangen  kann, wenn man 1     Mol        Nikotinsäurediäthyl-          amid    auf 1     Mol        Strontiumchlorid    einwirken  lässt. Die Reaktion kann in An- oder in Ab  wesenheit eines Lösungsmittels ausgeführt  werden.  



  Die neue Doppelverbindung bildet weisse  Kristalle. Sie ist in Alkohol und Aceton un  löslich, in Wasser aber leicht löslich.  



  Das neue Produkt soll sowohl zur Ab  scheidung und Reinigung der zu Grunde  liegenden     Pyridinverbindung,    wie auch zu  therapeutischen Zwecken Verwendung finden.  <I>Beispiel:</I>  Eine wässerige Lösung von 178 Teilen       Nikotinsäurediäthylamid    und     1"08    Teilen       Strontiumehlorid    dampft man zur Trockne  ein, wobei die gebildete Doppelverbindung  als weisses kristallines Pulver zurückbleibt.



      Procedure for the preparation of a double compound of the pyridine series. It has been found that a double compound of the pyridine series can be obtained if 1 mol of nicotinic acid diethylamide is allowed to act on 1 mol of strontium chloride. The reaction can be carried out in the presence or absence of a solvent.



  The new double compound forms white crystals. It is insoluble in alcohol and acetone, but easily soluble in water.



  The new product is intended to be used for separating and purifying the underlying pyridine compound as well as for therapeutic purposes. <I> Example: </I> An aqueous solution of 178 parts of nicotinic acid diethylamide and 1 "08 parts of strontium chloride is evaporated to dryness, the double compound formed remaining as a white crystalline powder.
