Procedure

0.59 mL (7.55 mmol) methanesulphonic acid chloride are added dropwise to a solution, cooled to 0° C., of 2.2 g (6.29 mmol) 2-{4-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-phenoxy}-ethanol and 1.74 mL (12.58 mmol) triethylamine in 25 mL THF. The reaction mixture is heated to RT and stirred for 2 h. To complete the reaction 5 mL pyridine are added and kept at RT for a further 18 h. The solvent is eliminated i.vac., the residue is combined with water and triturated with diethyl ether. The product precipitated is suction filtered and dried.
