A solution of methacryloyl isocyanate (11.1 g; 0.1 mol) in 1,2-dichloroethane (50 ml) was dropwise added to a solution of dry phenol (9.4 g; 0.1 mol) in chloroform (20 ml) under nitrogen stream while cooling with ice. After completion of the addition, chloroform and 1,2-dichloroethane were evaporated under reduced pressure. The residue (20.5 g) was recrystallized from a mixture of hexane and benzene to give phenyl N-methacryloylcarbamate as colorless needles. M.P., 94°-95° C.
