Reaction Conditions

Reaction Steps

3.4 g (0.024 mol) of chlorosulfonyl isocyanate are added dropwise at 25° C. to a solution of 3.45 g (0.02 mol) of 2-(2-chloroethoxy)phenol in 20 ml of xylene. When the dropwise addition is complete, the temperature is increased slowly to 140° C., and the mixture is refluxed for 2 hours. The mixture is cooled and the solvent as well as excess chlorosulfonyl isocyanate are removed on a rotary evaporator. The yellow oil which remains (5.6 g=100% of theory) is employed without further purification.
