Description
Verfahren zur Darstellung von Allylniorphin. Allylniorphin war bis jetzt nicht bekannt. Es wurde nun gefunden, dass mittelst eines Arylsulfosäure-Allylesters die Allylgruppe sich mit guter Ausbeute in das Morpbin einführen lässt, wenn man die Alkaliverbindung des Morphins mit dem Ai@ylsulfosiiure-Ailylester behandelt. Das neue Allylmorphin ist für sich therapeutisch wirksam; es bildet aber auch einen wertvollen Ausgangskörper für die Dar stellung neuer Morphinderivate.
<I>Beispiel</I> 1 Mol. (30 g) trockenes Morphin wird in einer Lösung von aus 1 Mol. (2,3 g) Natrium und 90 g absolutem Alkohol dargestelltem Äthylat aufgelöst und im Verlaufe von'/2-1- stündigem Rühren tropfenweise mit einer Lö sung von 1 Mol. (20 g) BenzolsulfosäLire-Allyl- ester in 40 g absoluten Alkohol versetzt, wobei die Temperatur zwischen 20 und 25' gehalten wird.
Nach einstündigem Stehen erwärmt man auf dem Wasserbade auf 40 , bis die Lösung Phenolphtalein nicht mehr rötet. Das Trennen des entstandenen Allyl- morphins vom unveränderten Alorphin ge schieht auf die bei der Äthylmorphindarstel- lung übliche Weise. Die freie Base kann ohne L'mkristallisieren in das Chlorhydrat übergeführt werden, welches mit Äther ver setzt, abgenutscht und mit Äther gewaschen, im Gewichte von 20-2-1 g erhalten wird.
Das vom Allylinorphin getrennte unveränderte Morphin kann zurückgewonnen werden.
Das Allylinoi-phinchlorhydrat kristallisiert mit 1 Mol. Wasser, welches es leicht verliert; es schmilzt, rasch erwärmt, bei 129-1311, langsam erwärmt bei 130-132 . Die Base kristallisiert finit 'j= Mol. Wasser und schmilzt bei 67--681'.
Process for the preparation of allylniorphine. Allylniorphine was not yet known. It has now been found that the allyl group can be introduced into the morphine with good yield by means of an arylsulfonic acid allyl ester if the alkali metal compound of morphine is treated with the aryl sulfonic acid ailyl ester. The new allyl morphine is therapeutically effective in itself; but it also forms a valuable starting material for the presentation of new morphine derivatives.
<I> Example </I> 1 mol. (30 g) of dry morphine is dissolved in a solution of ethylate prepared from 1 mol. (2.3 g) of sodium and 90 g of absolute alcohol and in the course of '/ 2-1 - Hours of stirring with a solution of 1 mol. (20 g) BenzolsulfosäLire-Allyl- ester in 40 g of absolute alcohol, the temperature is kept between 20 and 25 '.
After standing for one hour, the mixture is warmed to 40 on the water bath until the phenolphthalein solution is no longer reddened. The separation of the allyl morphine formed from the unchanged alorphine takes place in the usual way in the representation of ethyl morphine. The free base can be converted into the hydrochloride without recrystallization, which sets ver with ether, suction filtered and washed with ether, is obtained in a weight of 20-2-1 g.
The unchanged morphine separated from the allylinorphine can be recovered.
The Allylinoi-phinchlorhydrat crystallizes with 1 mol. Water, which it easily loses; it melts, heated rapidly, at 129-1311, slowly heated at 130-132. The base crystallizes finitely j = mol. Water and melts at 67--681 '.
