To a stirred solution of 3-(4-hydroxymethylphenyl)propionic acid ethyl ester (P5, 2.9 g, 13.9 mmol) in triethylamine (4.0 mL, 27.8 mmol) and dichloromethane (30 mL) was slowly added at 0° C. mesyl chloride (1.6 mL, 20.9 mmol). The solution was stirred at room temperature for 18 hours, then the solution was washed with 1N aqueous hydrochloric acid. The organic phase was dried (anhydrous magnesium sulfate) and concentrated to afford the title compound as an oil.
