실험 절차

To a solution of 5.1 g (29.97 mmol) of 2-(4-Fluoro-2-methoxy-phenyl)-ethanol in 30 ml of anhydrous dichloromethane was added at 0° C. 6.26 ml (44.95 mmol) of triethylamine and 3.5 ml (44.95 mmol) of methanesulfonyl chloride. The resulting mixture was stirred at 0° C. for 1 h. The mixture was then diluted with water and dichloromethane and extracted with dichloromethane. Organic layer was dried and evaporated to give 7 g(100%) of methanesulfonic acid 2-(4-fluoro-2-methoxy-phenyl)-ethyl ester.
