Description
Verfahren zur Herstellung eines diuretisch wirksamen substituierten 2,4-Diamino-1,3,5-i\iiä Im Hauptpatent ist ein Verfahren zur Herstellung eines neuen, diuretisch wirksamen substituierten 2,4-Diamino-1,3,5-triazins, näm lich des 2-(p-Chlor-anilino)-4-amino-1,3,5-tri- azins, beschrieben.
Es wurde gefunden, dass auch das entspre chende, bisher ebenfalls umbekannte Brom derivat eine hervorragende diuretische Wir kung aufweist.
Die neue Verbindung wird erfindungs gemäss derart'hergestellt, dass man auf 1-(p- Brom-phenyl)-biguanid einen Lberschuss an einer den Methinrest, -CH=, abgebenden Verbindung zur Einwirkung bringt.
Das Ausgangsmaterial, das 1-(p-Brom- phenyl-biguanid, kann nach bekannten Me thoden hergestellt werden; es wird zweck mässig in Form des Formiates verwendet. Als den Rest -CH= abgebende Verbindungen kommen neben Ameisensäure auch Salze der Ameisensäure, Ameisensäureester, Orthoamei- sensäureester, Formamid, Formamidin, Chloro form usw. in Betracht.
Die neue Base bildet weisse Kristalle vom Schmp. 259 bis 260 . Sie soll sowohl als Heil mittel wie auch als Zwischenprodukt für die Herstellung von Heilmitteln verwendet wer den.
<I>Beispiel:</I> > 15 g (0,05 Mol) 1-(p-Brom-phenyl)-bigua- nid-formiat werden mit 60 ml 86 % iger tech- nischer Ameisensäure während 4 Stunden ge- kocht und dann die Hälfte der Ameisensäure abdestilliert. Der Rest wird mit etwas Wasser verdünnt und mit Natronlauge lackmusalka-
lisch gemacht, worauf die Triazinbase in Form eines weissen, kristallinischen, in Wasser schwach löslichen Niederschlages ausscheidet. Man erhält 10,5 g Rohbase vom Schmp. 242 bis 243 . Durch Umkristallisieren aus ver- dünntem Alkohol erhält man die reine Base vorn Schmp. 259 bis 260 .
Das durch Behandlung der Base mit Salz säure erhältliche Hydrochlorid bildet nadel förmige Kristalle, ist in Wasser gut löslich und schmilzt bei 283 bis 284 .
Process for the production of a diuretically active substituted 2,4-diamino-1,3,5-i \ iiä In the main patent is a process for the production of a new, diuretically active substituted 2,4-diamino-1,3,5-triazine, namely Lich of 2- (p-chloro-anilino) -4-amino-1,3,5-triazine, described.
It has been found that the corresponding, hitherto unknown bromine derivative also has an excellent diuretic effect.
According to the invention, the new compound is produced in such a way that an excess of a methine residue, -CH =, releasing compound is brought into action on 1- (p-bromo-phenyl) -biguanide.
The starting material, 1- (p-bromophenyl-biguanide, can be prepared by known methods; it is expediently used in the form of the formate. In addition to formic acid, there are also salts of formic acid and formic acid esters as compounds releasing the radical -CH = , Orthoformic acid ester, formamide, formamidine, chloroform, etc. into consideration.
The new base forms white crystals with a melting point of 259 to 260. It is intended to be used both as a medicinal product and as an intermediate for the manufacture of medicinal products.
<I> Example: </I>> 15 g (0.05 mol) 1- (p-bromo-phenyl) -biguanide-formate are boiled with 60 ml of 86% technical formic acid for 4 hours and then half of the formic acid is distilled off. The rest is diluted with a little water and litmusalka with caustic soda.
made, whereupon the triazine base separates out in the form of a white, crystalline precipitate that is slightly soluble in water. 10.5 g of crude base with a melting point of 242 to 243 are obtained. Recrystallization from dilute alcohol gives the pure base with a melting point of 259 to 260.
The hydrochloride, which can be obtained by treating the base with hydrochloric acid, forms needle-shaped crystals, is readily soluble in water and melts at 283 to 284.
