Reaction Steps

0.24 g of p-toluenesulfonic acid monohydrate was added to a solution of 1.05 g of 3-phenyl-5-((tris(propan-2-yl)silyl)oxy)pentan-2-yl methanesulfonate in 15 mL of methanol, and the obtained mixture was then stirred at room temperature for 1 hour. Thereafter, ethyl acetate and a saturated sodium hydrogen carbonate aqueous solution were added to the reaction mixture. The organic layer was fractionated, and it was successively washed with water and a saturated sodium chloride aqueous solution, and was then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure, and the obtained residue was then purified by silica gel column chromatography (ethyl acetate/hexane=1/4 to 1/1), so as to obtain 0.56 g of 5-hydroxy-3-phenylpentan-2-yl methanesulfonate in the form of a colorless oily product.
