실험 절차
To a cooled (0° C.) solution of 3-bromo-5-fluoro-2-methyl-benzoic acid (3 g, 12.9 mmol) in dry THF (20 mL) was added borane THF complex (25.8 mL, 1 M in THF, 25.8 mmol) slowly. The resulting mixture was stirred at room temperature overnight, then quenched with MeOH and concentrated. The residue was purified by column chromatography to give (3-bromo-5-fluoro-2-methyl-phenyl)-methanol. 1H-NMR (400 MHz, CDCl3) δ ppm 7.25 (dd, J=8.6 Hz, J=3.1 Hz, 1H), 7.15 (dd, J=8.6 Hz, J=2.3 Hz, 1H), 4.71 (s, 2H), 2.33 (s, 3H).
