Versuchsvorschrift

One gram (1.0 g) of N-[2-(3,4-dimethoxyphenyl)ethyl]-2-(4-methylphenyl) acetamide (3.2 mmol), 1.68 g (9.64 mmol) of t-butoxybis(dimethylamino)methane and 15 ml of N,N-dimethylformamide were mixed and stirred at 90° C. for 3 hours and then at 110° C. for 3 hours. Water was added to the reaction mixture, which was followed by extracted with ethyl acetate, washed with saturated brine twice, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to give 1.20 g of crude N-[2-(3,4-dimethoxyphenyl)ethyl]-3-dimethylamino-2-(4-methylphenyl)acrylamide.
