YieldReaction ConditionsOperation in experiment
76%
Stage #1: at 20 - 80℃; for 2 h; Inert atmosphere
Stage #2: Reflux
Under argon protection, 11.2 g of acetic anhydride and 25.6 g were addedN - (2-methyl-4-oxapentan-2-yl) -3-morpholinopropionamideThe raw material is mixed with 250 ml of toluene, and the temperature is slowly increased from room temperature to 60 to 80 DEG C and stirred for 2 hours. After stirringMix and then add 0.2 g inhibitor BHT and 0.1 g cuprous chloride and 10.8 g triethylamine, and gradually warmed to reflux reactionNight, the reaction system was concentrated under reduced pressure to give the crude product which was directly separated by silica gel column chromatography with hexane-ethyl acetate14.1 grams of purified pure acrylamide (85percent yield) and 9.8 grams of pure N-acetylmorpholine (76percent yield).
