Procedure: Methanesulphonyl chloride (23 g.) was added dropwise to a stirred solution of 2-[2,6-dimethoxyphenoxy]ethanol (20 g.) (J. Med. Chem. 1969, 12, 326) in pyridine (50 ml.). The solution was left at room temperature for 60 hours, then the solvent evaporated under reduced pressure. The residue was taken up in chloroform, washed with water (3×100 ml.) and sodium bicarbonate solution (5%, 3×100 ml.), dried and the solvent evaporated. The residue was triturated with n-hexane and the solid collected to give 2-[2,6-dimethoxyphenoxy]-ethyl mesylate (11.3 g.) characterized spectroscopically. the solvent evaporated under reduced pressure washed with water (3×100 ml.) and sodium bicarbonate solution (5%, 3×100 ml.) dried the solvent evaporated The residue was triturated with n-hexane the solid collected
