Sodium borohydride (0.33 g) was added to a mixture of ethyl [4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]-acetate (1.33 g), tetrahydrofuran (10 mL) and ethanol (10 mL). The mixture was stirred at room temperature for 4 hrs, and water was added. The resulting mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=2/1) to afford the title compound (1.13 g).
