To a solution of acetamide (0.59 g; 10 mmol) in 1,2-dichloroethane (20 ml), a solution of methacryloyl isocyanate (1.11 g; 10 mmol) in 1,2-dichloroethane (10 ml) was dropwise added. After completion of the addition, pyridine (5 drops) was added to the solution, and then stirring was continued at room temperature for 12 hours. 1,2-Dichloroethane was evaporated under reduced pressure to give 1-methacryloyl-3-acetylurea (1.36 g), which was recrystallized from a mixture of benzene and hexane to give colorless needles. M.P., 92°-94° C.
