Participants

Reaction Steps

Morpholine (2 equivalents) is added to a well-stirred ice-cooled solution in dry ether of 3,3-dimethylacryloyl chloride (1 equivalent) and when addition is complete, the mixture is warmed for a few minutes. the mixture is then cooled, filtered, the solvent removed and the residue recrystallized from 60-80 petrol to give 3,3-dimethylacryloyl morpholine m.pt. 52°-4°.
