실험 절차

To 2-isopropenyloxazoline-4,5-dione hydrochloride (200 g; 1.14 mol), dichloroethane (800 g) was added, and the resultant mixture was heated to 60°-65° C. while stirring for about 5.5 hours. After cooling with water, the reaction mixture was distilled under reduced pressure to give methacryloyl isocyanate (25.3 g) and alpha-methyl-beta-chloropropionyl isocyanate (80.7 g).
