Description

  

  Verfahren zur Herstellung einer neuen Schiffsehen Base.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer neuen       Sehiffsehen    Base, welches dadurch     gekenn-          zeiehnet    ist, dass man auf     2,6-Dimethyl-4-          i        amino        -5-aminomethyl-pyrimidin        eine        das        Ra-          dikal    der Formel  
EMI0001.0012     
    liefernde Verbindung einwirken lässt.

   Als das       Radikal    der obigen Formel liefernde Verbin  dungen seien genannt:     p-Äthylureido-benz-          aldehvd,    p -     Äthylureido    -     benzaldeliy        dacetalc     oder     p-Äthylureido-benzaldehy        ddiaeylderivate.     



  Das so erhaltene     5-(p-Ätliylureidobenzal-          aminomethyl)-2,6-dimethyl-4-amino-py        rimidin,     das wahrscheinlich wenigstens in Lösung im       Gleiehgewicht    mit der Ringform 2,6-Diniethyl       2'-(p-äthylureido-phenyl)-1',2',3',4'-tetrahydro-          pyrimido-(5',6'    : 5,4)     -pyrimidin    steht, schmilzt  bei 168-169 . Das Verfahrensprodukt soll als       Chemotherapeuticum    und als Zwischenpro  dukt Verwendung finden.  



  <I>Beispiel:</I>  Zu einer Lösung von 10 g Natrium in  400     em"-        abs.    Methanol werden 49 g     2,6-Di-          niet.liyl-4-amino-    5 -     aminomethyl    -     p7    r     imidin-di-          hy        drochlorid    gegeben, das Ganze kurz zum  Sieden erhitzt, gekühlt und mit einer Lösung    von 42 g     p-Äthylureido-benzaldehyd    in 250     cm3          abs.    Methanol vermischt.

   Man kocht 15 Minu  ten, destilliert den Methanol im Vakuum ab,  versetzt den Rückstand mit 200     cm3        Dioxan     und kühlt unter Schütteln auf 0 . Das aus  gefallene     Produkt    wird abgesaugt und aus  Wasser     umkristallisiert.    Man erhält so 33 g,  das sind 460/ &  der Theorie, der bei 168-169   schmelzenden     p-Äthylureido-benzalverbindung     des     2,6-Dimethyl-4-amino-5-aminomethyl-pyr-          imidins.  



  Method of manufacturing a new marine base. The subject of the present patent is a process for the production of a new Sehiffsehen base, which is characterized in that one has the radical of the formula on 2,6-dimethyl-4-amino -5-aminomethyl-pyrimidine
EMI0001.0012
    supplying compound can act.

   The following compounds which provide the radical of the above formula may be mentioned: p-ethylureido-benzaldehyde, p-ethylureido-benzaldeliy dacetalc or p-ethylureido-benzaldehyde diaeyl derivatives.



  The 5- (p-Ätliylureidobenzal- aminomethyl) -2,6-dimethyl-4-aminopyrimidine, which is probably at least in solution in equilibrium with the ring form 2,6-diniethyl 2 '- (p-ethylureido-phenyl ) -1 ', 2', 3 ', 4'-tetrahydropyrimido- (5', 6 ': 5.4) -pyrimidine, melts at 168-169. The process product is intended to be used as a chemotherapeutic agent and as an intermediate product.



  <I> Example: </I> 49 g of 2,6-di-niet.liyl-4-amino-5-aminomethyl-p7 r imidine-di are added to a solution of 10 g of sodium in 400 em "- abs. Methanol - given hydrochloride, the whole thing briefly heated to the boil, cooled and mixed with a solution of 42 g of p-ethylureido-benzaldehyde in 250 cm3 of absolute methanol.

   It is boiled for 15 minutes, the methanol is distilled off in vacuo, the residue is mixed with 200 cm3 of dioxane and cooled to 0 while shaking. The precipitated product is filtered off with suction and recrystallized from water. This gives 33 g, that is 460% of theory, of the p-ethylureido-benzal compound of 2,6-dimethyl-4-amino-5-aminomethyl-pyrimidine which melts at 168-169.
