   Der Rest X kann in einem Halogenatom oder einem sonstigen für den Austausch gegen den basischen Rest geeigneten   reaktionsfähi-    gen Substituenten, wie z.

  Process for the production of a new basic substituted fatty acid amide.



   The subject of the present patent is a process for the preparation of a new basic substituted fatty acid amide, which is characterized by the fact that a compound of the formula
EMI1.1
 in which X is a reactive radical which is split off during the reaction, is reacted with diethylamine.



   The radical X can be in a halogen atom or another reactive substituent suitable for replacement with the basic radical, such as. B. an alkyl sulfonyloxy or aryl sulfonyloxy group, best hen. The exchange of group X against the diethylamino radical takes place z. B. by simply heating with diethylamine, optionally in the presence of a basic reacting Kon deusantsmittel or diethylamine in excess. The diethylaminoacetic acid-N- (2- o-methyl-phenoxy-ethyl-1) -methylamide is a colorless oil that boils below 0.09 mm at 139-140.



   The new amide will be used as a local anesthetic and as an intermediate for the production of other derivatives.



   Example: 24.2 g of chloroacetic acid-N- (2-o-methyl phenoxy-ethyl-1) -methylamide and 16.4 g of diethylamine are dissolved together in 200 em3 abs. Benzene heated on a water bath for 3 hours. The reaction mixture is extracted with 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 residue is distilled in a high vacuum.



   The diethylaminoacetic acid-N- (2-o-methyl-phenoxy-ethyl-1) -methylamide boiling below 0.09 mm at 139-140 is obtained in a yield of 70% of theory. Colorless oil, sparingly soluble in water, good in organic solvents and in dilute mineral acids.
