反応手順
To a solution of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (150 mg, 0.682 mmol) in DMF (5 mL) was added 60% NaH (136 mg, 3.41 mmol) and 2-bromoethyl methyl ether (0.13 mL, 1.363 mmol). The resulting solution was stirred at 50° C. overnight, cooled to ambient temperature, quenched with water, and extracted with EtOAc. The combined extracts were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated. The residue was purified by flash chromatography to give the title compound (114 mg, 60% yield).
