Participants

Reaction Steps

Sodium meta periodate (0.157 g) was added to a mixture of ethyl 3-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (0.075 g), water (1 mL) and tetra hydrofuran (4 mL) at room temperature with stirring, and the mixture was stirred at that temperature for 10 min. 2 mol/L hydrochloric acid (0.082 mL) was added, and the resulting mixture was stirred at that temperature for additional 2 hrs, then water and ethyl acetate were added. The organic layer was separated, washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to afford 4-ethoxycarbonyl-2-methoxyphenylboronic acid (0.049 g).
