Versuchsvorschrift

Furthermore, the reaction of 2,6-dimethylaniline at 120° to 125° C., in the presence of sodium bicarbonate as an acid-binding agent, with a three-fold molar excess of methyl 2-bromopropionate has been disclosed in U.S. Pat. No. 4,008,066. With this process, N-(1'-methoxycarbonylethyl)-2,6-dimethylaniline is obtained in a yield of 79.6% of theory.
