Procedure

0.267 ml (3.45 mmol) methanesulphonyl-chloride is added to o a solution of 584 mg (3.14 mmol) (3-methanesulphonyl-phenyl)-methanol and 0.66 ml (4.71 mmol) triethylamine in 6 ml dichloromethane. This reaction mixture is stirred at room temperature for 1 h and at 50° C. for additional 3 h. The reaction mixture is then poured into water and extracted twice with dichloromethane. The combined organic layers are washed with water and brine, dried, filtered and concentrated in vacuo to afford the title compound, which is used in the next step without further purification.
