A reaction flask was charged with morpholine (938 g, 10.8 mol) and potassium carbonate (K2CO3) (800 g, 5.8 mol) and heated to 40° C. with stirring. Propionaldehyde (500 g, 8.6 mol) was added dropwise while the temperature was kept under 60° C. with a water bath. After the completion of the addition, the reaction mixture was aged for two hours and filtered. The obtained filtrate was further distilled to provide 4-propenyl-morpholine (850 g, 6.7 mol).
