Description

  

  Verfahren zur Herstellung einer neuen     Schiffachen    Base.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer neuen       Sehiffsehen    Base, welches dadurch gekenn  zeichnet ist, dass man auf     2,4-Diamino-5-          aminometliyl-pyrimidin    eine das Radikal der  Formel  
EMI0001.0005     
    liefernde Verbindung einwirken lässt.

   Als das  Radikal der obigen Formel liefernde Verbin  dungen seien genannt:     p-Aeetamino-benz-          aldeliyd,        p-Acetamino-benzaldehydacetale    oder       -diaeylderivate    oder     p-Acetamino-benzalhalo-          genide.     



  Das so erhaltene     5-(p-Acetaininobenzal-          aminomethy    1) - 2,4 -     diamino    -     pyrimidin,    das       wahrscheinlich    wenigstens in Lösung im       ('.leieligewicht    mit der Ringform     2-Amino-\?'-          p    -     aeetaminophenyl        -1',2',3',4'-tetrahydropyr-          imido-(5',6':5,4)-pyrimidin    steht, schmilzt bei       196-1971'    unter Zersetzung. Das     Pikrat    der  Verbindung zersetzt sich ab 214 .

   Das Ver  fahrensprodukt soll als     Chemotherapeuticum     und als Zwischenprodukt Verwendung fin  den.  



  <I>Beispiel:</I>  Zu einer Lösung von 12,9g Natrium in  500     em3        abs.    Methanol werden 46 g     2,4-Di-          i        amino        -5-aminomethyl   <B>-</B>     pyrimidin-trihycli#ochlo-          rid    gegeben, das Ganze kurz zum Sieden er  hitzt, gekühlt und mit. einer Lösung von 30 g       p-Acetamino-benzaldehyd    in 500     cm3        abs.    Me-         thanol    vermischt.

   Man kocht 15     Minuten,-p-          stilliert    den Methanol im     Vakuum    ab, versetzt  den Rückstand mit 750     cm3    Wasser und kühlt  unter Schütteln auf 0 . Das ausgefallene Pro  dukt wird abgesaugt und aus Wasser umkri  stallisiert. Man erhält so 39 g, das sind 74 /o  der Theorie, der bei 196-197  unter Zerset  zung schmelzenden     p-Acetamino-benzalv        erbin-          dung    von     2,4-Diamino-5-aminomethyl-pyrimi-          din,    Das     Pikrat    der Base zersetzt sich ab 214 .



  Process for the production of a new shipping base. The subject of the present patent is a process for the preparation of a new Sehiffsehen base, which is characterized in that one has the radical of the formula on 2,4-diamino-5-aminometliyl-pyrimidine
EMI0001.0005
    supplying compound can act.

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



  The 5- (p-Acetaininobenzal- aminomethy 1) - 2,4 - diamino - pyrimidine thus obtained, which is probably at least in solution in the ('.leieligewicht with the ring form 2-Amino - \?' - p - aeetaminophenyl -1 ', 2 ', 3', 4'-tetrahydropyrimido (5 ', 6': 5.4) pyrimidine, melts with decomposition between 196 and 1971. The picrate of the compound decomposes from 214 onwards.

   The process product is intended to be used as a chemotherapeutic agent and as an intermediate product.



  <I> Example: </I> To a solution of 12.9g sodium in 500 em3 abs. To methanol, 46 g of 2,4-di-amino -5-aminomethyl pyrimidine-trihyclic chloride are added, the whole thing is briefly heated to the boil, cooled and with. a solution of 30 g of p-acetaminobenzaldehyde in 500 cm3 of abs. Methanol mixed.

   It is boiled for 15 minutes, the methanol is distilled off in vacuo, 750 cm3 of water are added to the residue and the mixture is cooled to 0 while shaking. The precipitated product is suctioned off and recrystallized from water. This gives 39 g, that is 74% of theory, of the p-acetaminobenzal compound of 2,4-diamino-5-aminomethylpyrimidine, the picrate of the base, which melts at 196-197 with decomposition decomposes from 214.
