Description
Verfahren zur Darstellung eines Alkaminesters einer aromatischen Aminokarbonsäure. Es wurde gefunden, dass der bisher un- bekannte Amirroberrzoylalkaminester von der Formel
EMI0001.0006
ein wertvolles Anaestheticum darstellt.
Man stellt den neuen Ester durch Er hitzen der p-Amirrobenzoesäurealkylester mit dem Alkamin dar.
<I>Beispiel: -</I> 1 Gewichtsteil p-AminobenzoesäLireäthyl- ester wird mit 3 Gewichtsteilen a-Dimethyl- amino-p-rnethyl-r-oaybutan 12 Stunden lang gekocht und dann das unveränderte Alkamin im Vakuum abdestilliert. Der Rückstand wird mit Salzsäure genau neutralisiert, die erhal tene Lösung mit Äther ausgeschüttelt, um unveränderten p-Amirrobenzoesäur-eester zu entfernen und hierauf das a-Dimethylamino- ss-methyl-r-(p-arninobenzoyl)-ogybutan mit Pottasche abgeschieden.
Die Base besitzt die im Hauptpatent an gegebenen Eigenschaften. Man erhält das selbe Produkt wie nach dem Verfahren des Hauptpatentes.
Process for the preparation of an alkamine ester of an aromatic aminocarboxylic acid. It has been found that the hitherto unknown Amirroberrzoylalkaminester of the formula
EMI0001.0006
represents a valuable anesthetic.
The new ester is prepared by heating the alkyl p-amirrobenzoate with the alkamine.
<I> Example: </I> 1 part by weight of p-aminobenzoesäLireäthyl- ester is boiled with 3 parts by weight of a-dimethylamino-p-methyl-r-oaybutane for 12 hours and then the unchanged alkamine is distilled off in vacuo. The residue is precisely neutralized with hydrochloric acid, the resulting solution is shaken out with ether in order to remove unchanged p-amirrobenzoic acid ester and then the a-dimethylamino-ss-methyl-r- (p-arninobenzoyl) -ogybutane is deposited with potash.
The base has the properties given in the main patent. The same product is obtained as in the process of the main patent.
