[OH:1][CH2:2][CH2:3][O:4][CH2:5][CH2:6][NH:7][C:8](=[O:11])[CH:9]=[CH2:10].[OH-].[K+].[CH3:14]I>O1CCCC1>[CH3:14][O:1][CH2:2][CH2:3][O:4][CH2:5][CH2:6][NH:7][C:8](=[O:11])[CH:9]=[CH2:10]N-[2-(2-hydroxyethoxy)ethyl]acrylamide (35.87 g), potassium hydroxide (15.2 g), tetrahydrofuran (100 g) and methyl iodide (33.58 g) were introduced into a 1 L eggplant type flask equipped with a reflux condenser and a magnetic rotor. A reaction was carried out at 45° C. for 2 hours and then for 2 hours at 60° C. as the mixture was being stirred. The salt that separated out was removed by filtration and the low boiling point components were removed by means of a rotary vacuum evaporator. Purification was performed by distillation under reduced pressure and N-[2-(2-methoxyethoxy)ethyl]acrylamide was obtained as a yellow transparent, viscous liquid.
