Procedure
At 0° C., (2-fluoro-ethoxy)-benzene (20 mmol) was added slowly to chlorosulfonic acid (200 mmol). The reaction mixture was stirred for 20 min at 0-5° C. and then warmed to room temperature, and finally stirred at 45° C. for 2 h. Then the reaction mixture was cautiously (!) added to ice water. The precipitate was filtered, washed with water and dried in a vacuum oven at 30° C. to give the title compound.
