2-(2-chloroethoxy)phenol

Conditions: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. When the dropwise addition the mixture is refluxed for 2 hours The mixture is cooled the solvent as well as excess chlorosulfonyl isocyanate are removed on a rotary evaporator is employed without further purification
