Description
Verfahren zur Darstellung einer Aeridiniumverbindung. Das Hauptpatent betrifft ein Verfahren zur Herstellung einer Acridiniumverbindung. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung des 2-Methoxy-6- chlor- 9 -(a-diäthylamino-ss,-oxypropylamino)- aeridinium-10-methylehlorid. Das Verfahren ist dadurch gekennzeichnet, dass man 2- Methoxy--6-chloracridinium-10 -methylchlorid,
das in 9-Stellung einen austauschfähigen Substituenten enthält, mit a-Diäthylamino- ss-oxy-y-aminopropan zur Umsetzung bringt. Die Umsetzung erfolgt zweckmässig unter Erwärmen und in Gegenwart eines Löse- oder Verdünnemittels wie Phenol. Aus tauschfähige Substituenten in der 9-Stellung der Acridinverbindung sind z. B. Halogen atome, Äther- oder Thioäthergruppen und der Sulfosäurerest.
Das so erhältliche Produkt ist ein hell gelbes, in Wasser leicht lösliches kristallines Pulver. Beim Erhitzen zersetzt es sich bei etwa 220'. Es soll pharmazeutische Anwen- ,dung finden.
<I>Beispiel:</I> 32,8 g 2-Methoxy-6,9-dichlor-10-methyl- acridiniumchlorid (erhalten durch Behandeln von 2-Methoxy-6-chlor-10-methylacridon vom E. 236 bis 237 mit Phosphorpentachlorid) werden in 120 g Phenol auf dem siedenden Wasserbade mit 15 g a-Diäthylamino-ss-oxy- y-aminopropan zur Reaktion gebracht. Aus der erkalteten Masse erhält man das Reak tionsprodukt nach Entfernen des Phenols durch ein organisches Lösemittel.
Man kann das Reaktionsgemisch auch so aufarbeiten, dass man zur Entfernung des Phenols in 2 n-Natronlauge einträgt, wobei sich die in Äther leicht lösliche Anhy.drobase des 2- Methoxy-6-chlor-9- <I>(a</I> -,diäthylamino-ss -oxy- y - propyla.mino)-10-methylaeridiniumhydroxyds abscheidet. Die weitere Reinigung geschieht durch Ausschütteln der ätherischen Lösung mit verdünnter Essigsäure.
Wiederausfällen .durch Ammoniak und erneutes Ausäthern. Eine Lösung von Chlorwasserstoff in Äther fällt aus der ätherischen Lösung der An hydrobase das Hydrochlorid des 2-Methogy- 6,chlor - 9 - (a,diäthylamino-ss - ogy- y -propyl- amino) - 10 - metlhylacridiniumchlorids. Das Salz löst sich leicht in Wasser mit gelber Farbe und zersetzt sich gegen 220'.
Process for the preparation of an aeridinium compound. The main patent relates to a process for the preparation of an acridinium compound. The subject of the present patent is a process for the preparation of 2-methoxy-6-chloro-9 - (a-diethylamino-ss, -oxypropylamino) - aeridinium-10-methylehlorid. The process is characterized in that 2-methoxy-6-chloroacridinium-10-methyl chloride,
which contains an exchangeable substituent in the 9-position, brings about reaction with a-diethylamino-ss-oxy-y-aminopropane. The reaction is conveniently carried out with heating and in the presence of a solvent or diluent such as phenol. From exchangeable substituents in the 9-position of the acridine compound are z. B. halogen atoms, ether or thioether groups and the sulfonic acid residue.
The product obtainable in this way is a light yellow crystalline powder which is easily soluble in water. When heated, it decomposes at about 220 '. It should find pharmaceutical use.
<I> Example: </I> 32.8 g of 2-methoxy-6,9-dichloro-10-methyl-acridinium chloride (obtained by treating 2-methoxy-6-chloro-10-methylacridone from E. 236 to 237 with phosphorus pentachloride) are made to react in 120 g of phenol on a boiling water bath with 15 g of a-diethylamino-ss-oxy-y-aminopropane. The reaction product is obtained from the cooled mass after removal of the phenol with an organic solvent.
The reaction mixture can also be worked up by introducing 2N sodium hydroxide solution to remove the phenol, the anhydride base of 2-methoxy-6-chloro-9- <I> (a </ I), which is easily soluble in ether > -, diethylamino-ss -oxy- y-propyla.mino) -10-methylaeridiniumhydroxyds separates. The further cleaning is done by shaking out the essential solution with dilute acetic acid.
Reprecipitation by ammonia and renewed etherification. A solution of hydrogen chloride in ether precipitates from the ethereal solution of the hydrobase the hydrochloride of 2-methogy- 6, chloro-9- (a, diethylamino-ss-ogy-y-propyl-amino) -10-methylhylacridinium chloride. The salt dissolves easily in water with a yellow color and decomposes about 220 '.
