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 (5 ml) was dropwise added at room temperature, and the reaction mixture was stirred at 80° C. for 3.5 hours. After cooling, 1,2-dichloroethane was evaporated under reduced pressure to give 1-methacryloyl-3-acetylurea (1.63 g), which was recrystallized from a mixture of benzene and hexane to give colorless needles. M.P., 92°-94° C.
