Procedure
To a stirred mixture of 4-chloro-2-methylphenol (24.7 g, 173 mmol) in acetone (10 ml), dichloroethane (25 ml) and water (45 ml) at 0-5° C. was added drop wise simultaneously 2-chloro-1-ethane sulfonyl chloride (28.2 g, 173 mmol) and a solution of 25% sodium hydroxide (60 g) during approximately one hour. The mixture was stirred for one hour at Sand for one hour at room temperature. Water was added and the mixture was extracted twice with DCM. The organic phase was dried with sodium sulphate, filtered and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel eluted with hexane-ethyl acetate which gave the title compound (33.4 g, 83%).
