Description
Verfahren zur Herstellung eines neuen basisch substituierten Fettsäureamides. Gegenstand des vorliegenden Patentes bil= det ein Verfahren zur Herstellung eines neuen basisch substituierten Fettsäureamides, wel- elies dadurch gekennzeichnet ist, dass man, eine Verbindung der Formel

in welcher X einen reaktionsfähigen, während der Reaktion sieh abspaltenden Rest bedeutet, mit Pyrrolidin iunsetzt.
Der Rest X kann in einem Halogenatom oder einem sonstigen für den Austausch gegen den basischen Rest geeigneten reaktionsfähi- 2en Substituenten, wie z. B. einer Alkylsul- fonyloxy- oder Arylsulfonyloxygruppe, beste hen. Der Austausch der Gruppe X gegen den Pyrralidinrest erfolgt z.
B. durch - einfaches Erwärmen mit Pyrrolidin, gegebenenfalls in Gegenwart eines basisch reagierenden Konden- aationsmit.tels oder von Pyrrolidin im Lrber- sehuss. Das N-(2-Phenoxyäthyl-1)-N-methyl- pyrrolidinoaeetamid ist ein farbloses, unter 0,08 mm bei<B>156-1570</B> siedendes Öl.
Das neue Amid soll als Lokalanästhetikum und als Zwischenprodukt zur Herstellung wei terer Derivate Verwendung finden.
Beispiel: <B>22,8</B> g N-(2-Phenoxyäthyl-1)-N-methyl-chlor- acetamid, 214,2 g Pyrrodidin und 10,1 g Tri- äthylamin werden zusammen in 150 cm?, abs. Benzol 3 Stunden auf dem Wasserbad erhitzt. Das Reaktionsgemisch wird mit. Wasser aus- gesehüttelt und dann mit 2n-Salzsäure ausge zogen.
Darauf wird der salzsaure Auszug mit Äther extrahiert, unter Eiskühlung mit konz. Natronlauge versetzt und das ausgeschiedene Öl in Äther aufgenommen. Nach dem Trock nen der Ätherauszüge über Pottasche wird der Äther verdampft und der Rüeksiand im Hoch vakuum destilliert.
Dabei gewinnt man das unter 0,08 mm, bei 156-157 siedende N-(2-Phenoxyäthyl-1)-N- methyl-pyrrolidinoacetamid in einer Ausbeute von 73<B>%</B> der Theorie. Farbloses Öl, schwer löslich in Wasser, gut in organischen Lösungs mitteln und. in verdünnten Mineralsäuren.
Process for the production of a new basic substituted fatty acid amide. The subject of the present patent forms a process for the preparation of a new basic substituted fatty acid amide, which is characterized in that one, a compound of the formula
EMI0001.0009
in which X denotes a reactive radical which is split off during the reaction, with pyrrolidine.
The radical X can be in a halogen atom or any other reactive substituent suitable for replacement with the basic radical, such as e.g. B. an alkylsulfonyloxy or arylsulfonyloxy group, best hen. The exchange of group X against the pyrralidine radical takes place, for.
B. by - simply heating with pyrrolidine, possibly in the presence of a basic reacting Konden- aationsmit.tels or pyrrolidine in excess. N- (2-Phenoxyethyl-1) -N-methylpyrrolidinoaetamide is a colorless oil that boils at <B> 156-1570 </B> below 0.08 mm.
The new amide is to be used as a local anesthetic and as an intermediate for the production of further derivatives.
Example: <B> 22.8 </B> g of N- (2-phenoxyethyl-1) -N-methyl-chloroacetamide, 214.2 g of pyrrodidine and 10.1 g of triethylamine are put together in 150 cm? , Section. Benzene heated on a water bath for 3 hours. The reaction mixture is with. Shaken out water and then extracted with 2N hydrochloric acid.
The hydrochloric acid extract is then extracted with ether, with conc. Sodium hydroxide solution was added and the separated oil was taken up in ether. After the ether extracts have dried over potash, the ether is evaporated and the Rüeksiand is distilled in a high vacuum.
The N- (2-phenoxyethyl-1) -N-methyl-pyrrolidinoacetamide, boiling below 0.08 mm and boiling at 156-157, is obtained in a yield of 73% of theory. Colorless oil, sparingly soluble in water, good in organic solvents and. in dilute mineral acids.
