Description
Verfahren zur Herstellung eines neuen s-Triazins
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines neuen s-Triazins mit wertvollen biologischen Eigenschaften.
Es wurde gefunden, dass man eine Verbindung mit gewebewachstumshemmender Wirksamkeit erhält, wenn man tetrameres Chlorcyan der Formel
EMI1.1
mit der vierfach molaren Menge Äthylenimin in Gegenwart eines säurebindenden Mittels und bei niedriger Temperatur zum 2-(N,N,N',N'-Bis-äthylen-guanidino)-4,6-bis- äthylenimino-s-triazin der Formel
EMI1.2
umsetzt. Die neue Verbindung hemmt z. B. die Entwicklung des Ascites-Carcinoms der Maus.
Die Umsetzung wird mit Vorteil in einem inerten organischen Lösungsmittel, wie z. B. Benzol oder Di äthyläther, bei Temperaturen um O0 vollzogen. Als säurebindendes Mittel kann ein Überschuss an Äthylenimin dienen, vorzugsweise verwendet man aber als solches eine tertiäre organische Base, wie z. B. Triäthylamin, Trimethylamin, Pyridin oder Dimethylanilin. Die erfindungsgemäss hergestellte neue Verbindung kristallisiert z. B aus Benzol-Diäthyläther in farblosen Prismen vom Zersetzungspunkt 115 bis 116". Sie ist in allen gebräuchlichen Lösungsmitteln sowie in Wasser löslich. Unter der Einwirkung von Säuren polymerisiert sie äusserst leicht, dagegen ist sie z. B. in wässrigen Pufferlösungen von neutraler bis schwach alkalischer Reaktion, z. B. 0,125 m Phosphatpufferlösung nach Soerensen, pH 7,4 beständig.
In den folgenden Beispielen bedeuten Teile Ge wichtsteile; diese verhalten sich zu Volumteilen wie g zu cm3. Die Temperaturen sind in Celsiusgraden angegeben.
Beispiel 1
Zu einer Lösung von 1,72 Teilen Athylenimin und 4,1 Teilen Triäthylamin in 30 Volumteilen abs. Äther wird unter schnellem Rühren eine Lösung von 2,5 Teilen tetrameren Chlorcyans in 20 Volumteilen abs.
Ather langsam zugetropft. Während der Umsetzung wird die Mischung mittels Eiskochsalzmischung von aussen auf - 5o gekühlt, und es wird ein trockener Stickstoffstrom durch das Reaktionsgefäss geleitet.
Nach 30 Minuten ist die Zugabe beendet, und das Gemisch wird noch 30 Minuten bei -50 weitergerührt. Man filtriert von den ausgefallenen Kristallen ab und extrahiert diese zweimal mit je 500 Volumteilen warmem abs. Äther. Man filtriert den Extrakt unter Stickstoff und engt das Filtrat im Vacuum ein, wobei das 2-(N,N,N',N'-Bis-äthylen-guanidino)-4,6-bis- äthylenimino-s-triazin auskristallisiert. Es kristallisiert aus Benzol-Äther in Prismen vom Zersetzungspunkt 115-116".
Beispiel 2
Zu einer Lösung von 1,75 Teilen laithylenimin und 4,2 Teilen Triäthylamin in 40 Volumteilen abs.
Benzol werden unter Rühren 2,5 Teile tetrameres Chlorcyan, gelöst in 20 Volumteilen abs. Benzol, langsam zugetropft. Die Temperatur wird durch äussere Kühlung bei höchstens + 10 gehalten, und es wird während der Umsetzung trockener Stickstoff durch das Reaktionsgefäss geleitet.
Nach 15 Minuten ist die Zugabe beendet, und die Mischung wird noch 60 Minuten bei +7O weitergerührt. Hierauf filtriert man unter Stickstoff vom Triäthylaminhydrochlorid ab und engt das Filtrat im Vakuum bei 406 ein. Beim Zusatz von Äther kristallisiert das 2-(N,N,N',N'-Bis-äthylen-guanidino)-4, 6-bis äthylenimino-s-triazin in schönen Prismen aus.
Aus abs. Benzol-Äther umkristallisiert, schmilzt es unter Zersetzung bei 114-116".
Process for the preparation of a new s-triazine
The present invention relates to a process for the preparation of a new s-triazine with valuable biological properties.
It has been found that a compound with tissue growth inhibiting activity is obtained when using tetrameric cyanogen chloride of the formula
EMI1.1
with four times the molar amount of ethyleneimine in the presence of an acid-binding agent and at low temperature to 2- (N, N, N ', N'-bis-ethylene-guanidino) -4,6-bis-äthylenimino-s-triazine of the formula
EMI1.2
implements. The new connection inhibits z. B. the development of ascites carcinoma of the mouse.
The reaction is advantageously carried out in an inert organic solvent, such as. B. benzene or diethyl ether, completed at temperatures around O0. An excess of ethyleneimine can serve as acid-binding agent, but preferably a tertiary organic base such as. B. triethylamine, trimethylamine, pyridine or dimethylaniline. The novel compound prepared according to the invention crystallizes, for. B from benzene diethyl ether in colorless prisms with a decomposition point of 115 to 116 ". It is soluble in all common solvents as well as in water. Under the action of acids it polymerizes extremely easily, on the other hand it is, for example, neutral to weak in aqueous buffer solutions alkaline reaction, e.g. 0.125 m phosphate buffer solution according to Soerensen, pH 7.4 resistant.
In the following examples, parts mean parts by weight; these are related to parts of volume as g to cm3. The temperatures are given in degrees Celsius.
example 1
To a solution of 1.72 parts of ethyleneimine and 4.1 parts of triethylamine in 30 parts by volume of abs. Ether becomes a solution of 2.5 parts of tetrameric cyanogen chloride in 20 parts by volume of abs with rapid stirring.
Ether slowly added dropwise. During the reaction, the mixture is cooled from the outside to -5 ° by means of an ice-cream mixture, and a stream of dry nitrogen is passed through the reaction vessel.
The addition is complete after 30 minutes and the mixture is stirred for a further 30 minutes at -50. The precipitated crystals are filtered off and extracted twice with 500 parts by volume of warm abs. Ether. The extract is filtered under nitrogen and the filtrate is concentrated in vacuo, the 2- (N, N, N ', N'-bis-ethylene-guanidino) -4,6-bis-ethyleneimino-s-triazine crystallizing out. It crystallizes from benzene ether in prisms with a decomposition point of 115-116 ".
Example 2
To a solution of 1.75 parts of ethyleneimine and 4.2 parts of triethylamine in 40 parts by volume of abs.
Benzene are 2.5 parts of tetrameric cyanogen chloride dissolved in 20 parts by volume of abs. Benzene, slowly added dropwise. The temperature is kept at a maximum of +10 by external cooling, and dry nitrogen is passed through the reaction vessel during the reaction.
The addition is complete after 15 minutes and the mixture is stirred for a further 60 minutes at + 70. The triethylamine hydrochloride is then filtered off under nitrogen and the filtrate is concentrated in vacuo at 406. When ether is added, the 2- (N, N, N ', N'-bis-ethylene-guanidino) -4, 6-bis-ethylenimino-s-triazine crystallizes out in beautiful prisms.
From abs. Recrystallized benzene ether, it melts with decomposition at 114-116 ".
