A solution of 14.6 g of diethylamine (0.2 m) in 100 ml of ethyl alcohol was added dropwise to a stirred solution of 19.6 g of ethyl propiolate (0.2 m) in 150 ml ethyl alcohol at room temperature. The exothermic reaction mixture was stirred at room temperature for 31/2 hours. The solvent was removed and the residue distilled through a short Vigreux column (boiling point 88° C./6 mm) to give 29.83 g (87 percent) of ethyl 3-(diethylamino)acrylate.
