Description
<B>Verfahren zur Herstellung eines neuen</B> Imidazoline. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen Imidazolins, welches dadurch gekennzeichnet. ist, dass man eine Verbindung der Formel
EMI0001.0003
worin X einen bei der Reaktion sich abspal tenden Rest bedeutet, z.
B. einen Ester von 2-Oxy-methyl-imidazolin mit starken anorga nischen oder organischen Säuren, wie zum Bei spiel Halogenwasserstoffsäuren, Alkyl- oder Arylsulfonsäuren, auf eine Verbindung der Formel
EMI0001.0008
worin R einen durch Hydrolyse in eine Oxy- gruppe überführbaren Rest, wie eine ver- ätherte oder veresterte Oxygruppe, z.
B. eine Methoxy-, Benzyloxy-, Aeetoxy- oder Benzoyl- oxygruppe, darstellt, einwirken lässt und gleichzeitig R durch Hydrolyse in die Oxy- gruppe überführt.
Die genannte Umsetzung kann in An- oder Abwesenheit von Verdünnungs- und/oder Kondensationsmitteln durchgeführt werden.
Das erhaltene 2-[N-(m-Oxy-phenyl)-N-phe- nyl-amino-methyl]-imidazolin ist neu. Es bil det leicht. Salze mit anorganischen oder orga- nischen Säuren, z. B. mit Halogenwasserstoff- säuren, wie der Salzsäure, mit Schwefelsäure, Phosphorsäure, Methansulfosäure oder Toluol- sulfosäure, Essigsäure und dergleichen, so zum Beispiel ein salzsaures Salz vom F. 191 bis 194 .
Beispiel: 113,6 Gewichtsteile N-(m-Acetoxy-phenyl)- phenyl-amin (hergestellt aus dem Natrium salz des N-(m-Oxyphenyl)-phenyl-amins und Acetylchlorid) und 77,5 Gewichtsteile 2-Chlor- methyl-imidazolin-hydrochlorid werden in 500 Volumteilen Xylol 12 Stunden zum Sieden er hitzt. Das Xylol wird abgegossen, der Rück stand in 400 Volumteilen warmem Wasser und Essigester gelöst.
Man trennt die Schichten und engt die wässerigen Anteile unter vermin dertem Druck ein. Durch Kühlen wird das Hydrochlorid des 2- [N- (m-Oxy-phenyl)-N- phenyl-amino-methyl]-imidazolins der Formel
EMI0001.0047
abgeschieden. Es schmilzt bei 191 bis 194 . Aus der wäs serigen Lösung des Hydrochlorids lässt sich die Base mit verdünntem Ammoniak gewin nen.
<B> Process for the production of a new </B> imidazoline. The subject of the present patent is a process for the preparation of a new imidazoline, which is characterized. is that you can get a compound of the formula
EMI0001.0003
wherein X is a residue that splits off in the reaction, e.g.
B. an ester of 2-oxy-methyl-imidazoline with strong inorganic or organic acids, such as, for example, hydrohalic acids, alkyl or aryl sulfonic acids, on a compound of the formula
EMI0001.0008
where R is a radical which can be converted into an oxy group by hydrolysis, such as an etherified or esterified oxy group, e.g.
B. a methoxy, benzyloxy, ethoxy or benzoyl oxy group, is allowed to act and at the same time R is converted into the oxy group by hydrolysis.
The reaction mentioned can be carried out in the presence or absence of diluents and / or condensation agents.
The 2- [N- (m-oxy-phenyl) -N-phenyl-amino-methyl] -imidazoline obtained is new. It forms easily. Salts with inorganic or organic acids, e.g. B. with hydrohalic acids, such as hydrochloric acid, with sulfuric acid, phosphoric acid, methanesulfonic acid or toluenesulfonic acid, acetic acid and the like, for example a hydrochloric acid salt with a melting point of 191 to 194.
Example: 113.6 parts by weight of N- (m-acetoxyphenyl) -phenyl-amine (made from the sodium salt of N- (m-oxyphenyl) -phenyl-amine and acetyl chloride) and 77.5 parts by weight of 2-chloromethyl Imidazoline hydrochloride is heated to boiling in 500 parts by volume of xylene for 12 hours. The xylene is poured off, the residue was dissolved in 400 parts by volume of warm water and ethyl acetate.
The layers are separated and the aqueous components are concentrated under reduced pressure. Upon cooling, the hydrochloride of 2- [N- (m-oxy-phenyl) -N-phenyl-aminomethyl] -imidazoline of the formula
EMI0001.0047
deposited. It melts at 191 to 194. The base can be obtained from the aqueous solution of the hydrochloride using dilute ammonia.
