"Verfahren zur Herstellung von 4-(Pyridyl)-tetrahydropyranen"
Die Erfindung bezieht sich, auf Pyridinderivate und deren Herstellung und insbesondere auf neue substituierte Pyridine sowie auf ein Verfahren zur Herstellung von substituierten 'Pjridinen. , ;
Gemäß der Erfindung werden als. neue Verbindungen 4-(Pyridyl)-tetrahydropyrane vorgeschlagen. Die. Tetrahydropyranylgruppe
kann an das. Kohlenstoffatom in der 2-, 3- oder 4--S te llung
des Pyridinkerns gebunden sein.
609845/0993
Unsubstituierte 4-(Pyridyl tetrahydropyrane besitzen die folgende allgemeine Strukturformel:
In den Bereich der Erfindung fallen auch Verbindungen, die diese Grundformel aufweisen, aber ein oder mehrere Substituenten enthalten, wie z.B. Alkyl- oder Alkoxy gruppen im Pyridylkern und/oder Tetrahydropyranylkern.
4—(Pyridyl)tetrahydropyrane können dadurch hergestellt werden, daß man einen 2l-Halogenäthyl-3-(pyridyl)propyläther mit einer aktiven Alkalimetallverbindung umsetzt. Die Reaktionsteilnehmer werden vorzugsweise in äquimolaren Mengen und vorzugsweise bei einer Temperatur im Bereich von -10 bis -800C in Lösung in einem flüssigen Ammoniak enthaltenden Medium umgesetzt. Jedoch kann die Reaktion in Abwesenheit eines Lösungsmittels oder in anderen Lösungsmitteln als flüssigem Ammoniak ausgeführt werden, beispielsweise in Kohlenwasserstoffen und Äthern, in welchen Fällen höhere Temperatüren, beispielsweise bis zu 4-00C, verwendet werden können. Höhere Temperaturen können auch dadurch erreicht werden, daß man die Reaktion unter überatmosphärischem Druck ausführt. Die bevorzugten aktiven Alkalimetallverbindungen sind Alkalimetallamide, insbesondere Natriumamid.
Das 4—(Pyridyl)tetrahydropyran kann aus dem Reaktionsgemisch durch herkömmliche Techniken isoliert werden, beispielsweise dadurch, daß man den Metallamidüberschuß durch Zusatz eines Ammoniumsalzes zerstört, das resultierende-Produkt mit einem organischen Lösungsmittel, das bei gewöhnlichen Temperaturen flüssig ist, wie z.B. Äther, extrahiert, die organische Schicht mit Wasser wäscht und das organische Lösungsmittel und das Produkt durch Destillation trennt.

Zu 1 1 gerührtem flüssigem Ammoniak wurden 0,1 g Eis en (III)-nitrat und dann 20,0 g Kaliummetall in 1 g wiegenden Stücken während eines Zeitraums von 30 min zugegeben. Zur resultierenden Losung wurden 46,6 g gammä-Picolinτwährend eines Zeitraums von 3 min zugesetzt, worauf sich eine tiefgelbe Farbe entwickelte. -
Die Losung wurde zu einer gerührten Lösung von 72,0 g 2,2'-DiCchloroäthyl)äther in Λ 1 flüssigem Ammoniak mit einer solchen Geschwindigkeit (gesamte Zugabezeit 20 min) zugegeben, daß keine gelbe Farbe bestehen blieb. Diese Lo&ung wurde mit "Lösung A" bezeichnet.
Zu Λ 1 gerührtem flüssigem Ammoniak wurden 0,1 g Eisen(III)-nitrat und dann 20,0 g Zaliummetall in Igwiegenden Stücken während eines Zeitraums von 30min zugegeben. Die resultierende Lösung wurde 20 min gerührt und zur Lösung A mit einer solchen Geschwindigkeit zugegeben, daß sich nur eine blaßgelbe Farbe entwickelte. Das Gemisch wurde 1 st- gerühmt, und dann wurden 20 g Ammoniumchlorid langsam zugesetzt, worauf noch 1 1 Äther zugegeben wurde» Das GemischI wurde auf Raumtemperatur erwärmen gelassen, filtriert und mit Wasser gewaschen. Das Lösungsmittel wurde entfernt, und der Rückstand wurde destilliert4 wobei 30 g 4-(4l-i^ridyl)tetrahydroKrran mit den folgenden Eigenschaften erhalten wurden:
