Description

  

  Verfahren     zur    Herstellung     eines    neuen     Pyrimidinderivates.       Gegenstand des vorliegenden Patentes bil  det ein Verfahren zur Herstellung eines neuen       Pyrimidinderivates,    welches dadurch gekenn  zeichnet ist, dass man ein     Pyrimidinderivat     der Formel  
EMI0001.0006     
    in welcher X einen durch Reduktion in die       Aminomethylgrnppe        überführbaren    Rest be  deutet, mit einem     Reduktionsmittel    behandelt.  



  Der Rest X kann beispielsweise in einer       Cyanogruppe    oder     einer        Carbamidogruppe    be  stehen. Im ersteren Falle kann die     Cyano-          gruppe    leicht mit     Raney-Nickel    und Wasser  stoff vorteilhaft in     alkoholischem.        Ammoniak     als Lösungsmittel reduziert werden oder auch  mit     Lithiumaluminiumhydrid    in Äther,     Tetra-          hydrofuran    usw.  



  Die     Carbamidogruppe    kann mit Hilfe von       Alkali-aluminium-    oder     -borhydriden    in die       Aminomethylgruppe    übergeführt werden.  



  Das so erhaltene 2 -     Methylmercapto    -     4-          amino-5-aminomethyl-pyrimidin    bildet farb  lose Kristalle, die bei 96-98  schmelzen. Es  soll als     Chemotherapeutikum    und als Zwi  schenprodukt verwendet werden.

      <I>Beispiel:</I>  50 g 2 -     Methylmercapto    - 4 -     amino    - 5 -     cyan-          pyrimidin    in 500     em3        Tetrahydrofuran    wer-    den     unter    Eiskühlung und Rühren in eine  Lösung von 40 g     Lithiilmaluminiumhydrid    in  500     em3        Tetrahydrofuran    eingetropft. Man       turbiniert    das Ganze einige Stunden     und    lässt  dann 2.4 Stunden stehen. Nach dem Versetzen  der Reaktionslösung mit Wasser wird filtriert  und das Filtrat alkalisch gemacht.

   Das Aus  gefallene     wird    nach dem Trocknen aus     Benzol          umkristallisiert.    Man erhält so das     2-Benzyl-          mercapto-4-amino-5-aminomethyl-pyrimidin    in  farblosen, bei 96-98  schmelzenden Kristal  len.



  Process for the preparation of a new pyrimidine derivative. The subject of the present patent bil det a process for the preparation of a new pyrimidine derivative, which is characterized in that a pyrimidine derivative of the formula
EMI0001.0006
    in which X denotes a radical which can be converted into the aminomethyl group by reduction, treated with a reducing agent.



  The radical X can be, for example, in a cyano group or a carbamido group. In the former case the cyano group can easily be mixed with Raney nickel and hydrogen, advantageously in alcoholic. Ammonia can be reduced as a solvent or with lithium aluminum hydride in ether, tetrahydrofuran etc.



  The carbamido group can be converted into the aminomethyl group with the aid of alkali aluminum or borohydrides.



  The 2-methylmercapto-4-amino-5-aminomethyl-pyrimidine obtained in this way forms colorless crystals which melt at 96-98. It should be used as a chemotherapeutic agent and as an intermediate product.

      Example: 50 g of 2-methylmercapto-4-amino-5-cyano-pyrimidine in 500 cubic meters of tetrahydrofuran are added dropwise to a solution of 40 g of lithium aluminum hydride in 500 cubic meters of tetrahydrofuran with ice-cooling and stirring. You turbine the whole thing for a few hours and then let it stand for 2.4 hours. After adding water to the reaction solution, it is filtered and the filtrate is made alkaline.

   The precipitated is recrystallized from benzene after drying. The 2-benzyl mercapto-4-amino-5-aminomethyl-pyrimidine is thus obtained in colorless crystals which melt at 96-98.
