Procedure

4-(2,2-Dimethoxyethoxy)phenol (0.05 mole) dissolved in benzene (10 ml) is charged into a glass reaction flask equipped with a mechanical stirrer. 3-Allylphenyl isocyanate (0.06 mole) and triethylamine (3 drops) are then added, and the resulting mixture is stirred at room temperature for a period of about 6 hours. The mixture is stripped of solvent and unreacted isocyanate to yield the desired product O-[4-(2,2-dimethoxyethoxy)phenyl] N-3-allylphenylcarbamate as the residue.
