  Verfahren zur Herstellung eines substituierten     2,4-Diamino-1,3,5-triazins.       Gegenstand vorliegenden Patentes bildet  ein Verfahren zur Herstellung eines substi  tuierten     2,4-Diamino-1,3,5-triazins.    Das Ver  fahren ist dadurch gekennzeichnet, dass man       1-(Cyclopentyl)-biguanid    mit einer zur     Tri-          azinringbildung    geeigneten, den Rest     HC=@    ab  gebenden Verbindung, wie z.

   B. mit Ameisen  säureester,     Formamid,        Formamidin,    Chloro  form,     Orthoameisensäureester,    zum     2-Amino-          4-cyelopentylamino-1,3,5-triazin    umsetzt. Die  erhaltene neue Base schmilzt bei 1640     und    soll  als Heilmittel oder Zwischenprodukt für die  Herstellung von Heilmitteln     verwendet    wer  den.  



  <I>Beispiel:</I>  43 Teile der fein gepulverten     Kupferkom-          plexverbindung    des     1-Cyclopentyl-biguanid-          sulfates    werden in einer Lösung von 8 Teilen       Natriumsulfid    in 120 Teilen Methanol 48  Stunden bei Raumtemperatur geschüttelt.  Das ausgefallene Kupfersulfid wird unter  Ausschluss der atmosphärischen Kohlensäure       abzentrifugiert,    die klare,     methylalkoholische     Lösung mit 15 Teilen     Äthylformiat    versetzt  und 2     Stunden    auf     601)    erwärmt.

   Nach Ab  destillieren des Methanols wird der Rück-    stand mit warmem Wasser verrührt, das da  bei anfallende     2-Amino-4-cyclopentylamino-          1,3,5-triazin        abgenutscht,    mit Wasser ge  waschen und getrocknet. Es     schmilzt    bei 1640.  



  Zur gleichen Verbindung gelangt man  auch durch     Umsetzung    von     1-Cyclopentyl-bi-          guanid    mit     Formamid.  



  Process for the preparation of a substituted 2,4-diamino-1,3,5-triazine. The subject of the present patent forms a process for the preparation of a substituted 2,4-diamino-1,3,5-triazine. The process is characterized in that 1- (cyclopentyl) biguanide with a suitable for triazine ring formation, the remainder HC = @ from giving compound such.

   B. with formic acid ester, formamide, formamidine, chloro form, orthoformic acid ester, to the 2-amino-4-cyelopentylamino-1,3,5-triazine. The new base obtained melts at 1640 and is said to be used as a remedy or an intermediate in the manufacture of remedies.



  <I> Example: </I> 43 parts of the finely powdered copper complex compound of 1-cyclopentyl biguanide sulfate are shaken in a solution of 8 parts of sodium sulfide in 120 parts of methanol for 48 hours at room temperature. The precipitated copper sulfide is centrifuged off with the exclusion of atmospheric carbon dioxide, the clear, methyl alcoholic solution is mixed with 15 parts of ethyl formate and heated to 601) for 2 hours.

   After the methanol has been distilled off, the residue is stirred with warm water, the 2-amino-4-cyclopentylamino-1,3,5-triazine which is produced is filtered off with suction, washed with water and dried. It melts at 1640.



  The same compound is also obtained by reacting 1-cyclopentyl biguanide with formamide.
