Description

  

  Verfahren zur Herstellung einer neuen Schiffsehen Base.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer neuen  Schiffsehen Base, welches dadurch gekenn  zeichnet ist,     da.ss    man auf     2-Benzylmercapto-          4-amino    - 5 -     aminomethyl    - 6 -     methyl    -     py        rimidin     eine das Radikal der Formel  
EMI0001.0008     
         liefernde    Verbindung einwirken lässt.

   Als das  Radikal der obigen Formel liefernde Verbin  dungen seien genannt:     p-Acetamino-benzalde-          hyd,        p-Acetamino-benzaldehydacetale    oder     -di-          acylderivate    oder     p-Acetamino-benzalhaloge-          nide.     



  Das so erhaltene     5-(p-Aeetaminobenzal-          amin        omethyl)        -2-benzy        lmercapto-4-amino-6-me-          thyl.-pyrimidin,    das wahrscheinlich wenigstens  in Lösung im Gleichgewicht mit der Ring  form     2-Benzylmercapto-6-methyl-2'-p-acet-          aminophenyl    - 1',2',3',4' -     tetrahydropyrimido-          (5',6'    :

       5,4)-pyrimidin    steht, schmilzt bei 133  bis     7.35 .    Das Verfahrensprodukt soll als       Chemotherapeuticum    und als     Zwisehenpro-          clukt    Verwendung finden.

      <I>Beispiel:</I>  Eine Lösung von 20 g     2-Benzylmereapto-4-          a        mino    - 5 -     aminomethyl    -     6-znethyl-pyrimidin    in       Methanol        wird        mit        einer        Lösung        von        1.2,5        g            p-Acetainino-benzaldehyd    in 200     em3        abs.    Me  thanol vermischt.

   Man kocht 15 Minuten, de  stilliert den Methanol im Vakuum ab, versetzt  den Rückstand mit 200     em3    Wasser und kühlt  unter Schütteln auf 0 . Das ausgefallene Pro  dukt wird abgesaugt und aus Äthanol     umkri-          stallisiert.        Man        erhält        so        19        g,        das        sind        61%     der Theorie,

   der bei 133-135  schmelzenden       p-Acetamino-benzalverbindung    von     2-Benzyl-          mercapto    -4-     amino    -.5 -     aminomethyl    - 6-     methyl-          pyrimidin.  



  Method of manufacturing a new marine base. The subject of the present patent is a process for the preparation of a new Schiffsehen base, which is characterized by the fact that 2-benzylmercapto-4-amino-5-aminomethyl-6-methyl-pyrimidine is a radical of the formula
EMI0001.0008
         supplying compound can act.

   The following compounds which provide the radical of the above formula may be mentioned: p-acetaminobenzaldehyde, p-acetaminobenzaldehyde acetals or -diacyl derivatives or p-acetaminobenzalhalogenides.



  The 5- (p-ethaminobenzalamine omethyl) -2-benzyl mercapto-4-amino-6-methyl-pyrimidine obtained in this way, which is probably at least in solution in equilibrium with the ring form 2-benzylmercapto-6-methyl -2'-p-acet-aminophenyl - 1 ', 2', 3 ', 4' - tetrahydropyrimido- (5 ', 6':

       5,4) pyrimidine, melts at 133 to 7.35. The process product is intended to be used as a chemotherapeutic agent and as an intermediate product.

      <I> Example: </I> A solution of 20 g of 2-benzylmereapto-4- a mino - 5 - aminomethyl - 6-methyl-pyrimidine in methanol is mixed with a solution of 1.2.5 g of p-acetainino-benzaldehyde in 200 em3 abs. Methanol mixed.

   The mixture is boiled for 15 minutes, the methanol is distilled off in vacuo, the residue is treated with 200 cubic meters of water and cooled to 0 while shaking. The precipitated product is filtered off with suction and recrystallized from ethanol. You get 19 g, that's 61% of theory,

   the p-acetaminobenzal compound of 2-benzyl mercapto -4-amino -.5-aminomethyl-6-methyl-pyrimidine, which melts at 133-135.
