Reaction Conditions

Reaction Steps

A 2 mol/L aqueous solution of sodium hydroxide (2.14 mL) was added to a solution of ethyl[2-ethoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]acetate (0.15 g) in ethanol (10 mL), and the resulting mixture was stirred at 60° C. for 3 hrs. Water and ethyl acetate were added to the reaction mixture. The aqueous layer was separated, washed with ethyl acetate, made acidic with the addition of 2 mol/L hydrochloric acid, and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to afford the title compound (0.066 g).
