A solution of methacryloyl isocyanate (11.1 g; 0.1 mol) in 1,2-dichloroethane (50 ml) was dropise added to dry benzyl alcohol (10.8 g; 0.1 mol) under nitrogen stream while cooling with ice. After completion of the addition, 1,2-dichloroethane was evaporated under reduced pressure. The residue (21.8 g) was recrystallized from a mixture of hexane and benzene to give benzyl N-methacryloylcarbamate as colorless needles. M.P., 109°-110° C.
