Procedure
0.46 mL of methanesulfonyl chloride was added dropwise to a solution of 1.0 g of 3-phenyl-5-((tris(propan-2-yl)silyl)oxy)pentan-2-ol and 1.67 mL of triethylamine in 10 mL of an ethyl acetate at a temperature of 5° C. to 10° C., and the obtained mixture was then stirred at room temperature for 5.5 hours. Thereafter, ethyl acetate and water were added to the reaction mixture. The organic layer was fractionated, and it was washed with a saturated sodium chloride aqueous solution and was then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure, so as to obtain 1.2 g of 3-phenyl-5-((tris(propan-2-yl)silyl)oxy)pentan-2-yl methanesulfonate in the form of a yellow oily product.
