To a solution of (3-acetyl-2-fluorophenyl)boronic acid (10.0 g, 0.055 mol) in tetrahydrofuran (160 mL) was added glacial acetic acid (60 mL). The resulting mixture was cooled to 0° C. before hydrogen peroxide (50% aqueous solution, 8 mL) was added. The resulting mixture was allowed to come to room temperature and stirred for 5 h. The mixture was evaporated and the residue was dissolved in ethyl acetate, washed with hydrochloric acid (0.5N), water and brine. The organic phase was dried, filtered and evaporated which afforded 1-(2-fluoro-3-hydroxy-phenyl)-ethanone (8.50 g, 100%) as a white solid.
