Description
Verfahren zur Darstellung eines Aralkylamins. Es wurde gefunden,. dass man nach dem im Hauptpatent beschriebenen Verfahren 4- Methoxy-l-benzylamin herstellen kann, wenn man an Stelle des dort verwendeten Benzols 4-Methoxybenzol verwendet. <I>Beispiel:</I> In 324 Teilen Methoxybenzol löst man 195 Teile co-Chlormethylphtalimid, wobei, wie ersichtlich, das Methoxybenzol, das gleich zeitig Lösungsmittel ist, im Überschuss vor handen ist. Man gibt 10 Teile Chlorzink, das als Katalysator dient; hinzu und erwärmt bis auf 1201' C.
Beim Aufarbeiten erhält man 4-Methoxybenzylphtalimid in fast theore tischer Ausbeute in Kristallen vom Schmelz punkt 1040. 50 Teile der Verbindung 'wer den mit 50 Teilen Alkohol, 100 Teilen 35 % iger Natriumhydroxydlösung und 200 Teilen Wasser kalt 2 Stunden lang gerührt. Dann wird mit verdünnter Salzsäure ange säuert und der Alkohol verjagt und etwa ausgeschiedenes 01 durch Wasserzusatz in Lösung gebracht. Bei der Aufarbeitung erhält man das 4-Methoxy-l-benzylaminchlorhydrat, durch Zusatz von Natriumhydroxyd und Aus- äthern die freie Base.
Das erhaltene, an sich bekannte Produkt soll als Zwischenprodukt bei der Darstellung technisch wichtiger Stoffe, wie Riechstoffe und Heilmittel, Verwendung finden.
Process for the preparation of an aralkylamine. It was found,. that 4-methoxy-1-benzylamine can be prepared by the process described in the main patent if 4-methoxybenzene is used instead of the benzene used there. <I> Example: </I> 195 parts of co-chloromethylphthalimide are dissolved in 324 parts of methoxybenzene, whereby, as can be seen, the methoxybenzene, which is also a solvent, is present in excess. 10 parts of zinc chloride, which serves as a catalyst, are added; added and heated to 1201 ° C.
When working up, 4-methoxybenzylphthalimide is obtained in almost theoretical yield in crystals with a melting point of 1040. 50 parts of the compound 'who is stirred with 50 parts of alcohol, 100 parts of 35% sodium hydroxide solution and 200 parts of water for 2 hours while cold. Then it is acidified with dilute hydrochloric acid and the alcohol is chased away and any excreted oil is brought into solution by adding water. The work-up gives 4-methoxy-1-benzylamine chlorohydrate, and the free base is obtained by adding sodium hydroxide and ether.
The product obtained, known per se, is intended to be used as an intermediate product in the preparation of technically important substances such as fragrances and medicinal products.
