Procedure
To [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid ethyl ester (0.100 g, 0.31 mmol) and iodomethane (0.04 mL, 0.63 mmol) in THF (5 mL) at −78° C. was added sodium hexamethyldisilazane (1M in THF; 0.63 mL, 0.63 mmol). The reaction was warmed to room temperature and stirred under N2 for 1 hour, and then quenched with H2O and partitioned between EtOAc and H2O. The aqueous layer was separated and extracted with EtOAc, and the combined organic layers were dried over MgSO4, filtered, and concentrated to give the title compound.
