Reaction Steps
A warm solution of methacrylamide (21.25 g) in dichloroethane (90 ml) was dropwise added in 1 hour to oxalyl chloride (34.5 g) kept at room temperature (20° C.) while stirring. The resultant mixture was cooled with water to room temperature. The produced 2-isopropenyloxazoline-4,5-dione hydrochloride (37 g) was collected by filtration under suction, washed with hexane and dried under reduced pressure. Decomposition temperature, 102° to 103° C.
