Description
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.
