Description
Verfahren zur Darstellung eines Acridinderivates. Gegenstand vorliegender Erfindung ist ein Verfahren zurDarstellung eines als Arznei mittel verwendbaren Acridinderivates. Das Verfahren ist dadurch gekennzeichnet, dass man eine 2-aYIethylmercapto-6-methylacridin- verbindung, die in der 9-Stellung einen aus tauschfähigen Substituenten enthält, mit a Diäthylamino-ö-amirroperrtan umsetzt. Der austauschfähige Substituent kann z.
B. ein Halogenatom, eine Alkoxy- oder Aryloxy-, eine Mercapto-, substituierte Mercapto- oder Sulfonsäuregruppe sein. Die Umsetzung er folgt zweckmässig unter Erwärmen und in Gegenwart eines Löse- oder Verdünnemittels, wie z. B. Phenol.
<I>Beispiel:</I> 27,4g 2-Methylmercapto-6-methyl. 9-chlor- acridin werden im siedenden Wasserbade mit 100 g Phenol zusammengeschmolzen und zur Schmelze 17 g a-Diathylamino-d-amino- pentan zugetropft. Neich einstündigem Er- hitzen auf 90-100o wird die Reaktions mischung in 1000 cm3 2n-Natronlauge ein getragen und die ausgeschiedene Base in Äther aufgenommen.
Die ätherische Lösung wird mit 10 % iger Essigsäure ausgezogen und die essigsaure Lösung nach Zusatz von Natronlauge wieder ausgeäthert. Aus der so gewonnenen ätherischen Lösung der neuen Base wird mit einer ätherischen Lösung von Zitronensäure das zitronensaure Salz des 2- AZethylmercapto-6-methyl-9 - (a-diäthylamino- 8-pentylamino)-acridins erhalten. Es ist ein gelbes Kristallpulver, das sich in Wasser und Alkohol spielend löst.
Aus der wässrigen Lösung fällt verdünnte Natronlauge, Natrium- carbonat- oder Ammoniaklösung die freie Base als gelbes 01 aus, das spielend in Äther, Methylenchlorid, Benzol, Alkohol usw. löslich ist.
Zur Darstellung von 2 Methylmercapto- 6-methyl-9-chloraeridin (zitronengelbe Kri stalle aus Benzol vom E.143 0) wird 4-Methyl- 2-chlorbenzoasäure mit 4-AminothiopheDyl- methyläther zur 4'-Methyl-mercapto-3-methyl- diphenylamin-6-carbonsäure (aus Benzol fast farblose Kristalle vom F.190 kondensiert, es wird dann ringgeschlossen und chloriert.
Process for the preparation of an acridine derivative. The present invention relates to a process for the preparation of an acridine derivative which can be used as a medicament. The process is characterized in that a 2-aYethylmercapto-6-methylacridine compound, which in the 9-position contains one of exchangeable substituents, is reacted with a diethylamino-δ-amirropulfan. The exchangeable substituent can e.g.
B. be a halogen atom, an alkoxy or aryloxy, a mercapto, substituted mercapto or sulfonic acid group. The implementation he follows conveniently with heating and in the presence of a solvent or diluent, such as. B. phenol.
<I> Example: </I> 27.4 g of 2-methylmercapto-6-methyl. 9-chloro-acridine are melted together with 100 g of phenol in a boiling water bath and 17 g of a-diethylamino-d-aminopentane are added dropwise to the melt. After just one hour of heating to 90-100 °, the reaction mixture is introduced into 1000 cm3 of 2N sodium hydroxide solution and the base which has separated out is taken up in ether.
The ethereal solution is extracted with 10% acetic acid and the acetic acid solution is extracted with ether again after adding sodium hydroxide solution. From the thus obtained ethereal solution of the new base, the citric acid salt of 2-A-methylmercapto-6-methyl-9 - (a-diethylamino-8-pentylamino) acridine is obtained with an ethereal solution of citric acid. It is a yellow crystal powder that easily dissolves in water and alcohol.
Dilute sodium hydroxide, sodium carbonate or ammonia solution precipitates out of the aqueous solution, the free base precipitates as yellow oil, which is easily soluble in ether, methylene chloride, benzene, alcohol, etc.
To prepare 2-methylmercapto-6-methyl-9-chloraeridin (lemon-yellow crystals from benzene from E. 143 0), 4-methyl-2-chlorobenzoic acid with 4-aminothiopheedylmethyl ether gives 4'-methyl-mercapto-3-methyl - Diphenylamine-6-carboxylic acid (almost colorless crystals of F.190 condensed from benzene, it is then ring-closed and chlorinated.
