LAH (987 mg, 26 mmol) was added slowly to a solution of 2-amino-6-fluoro-benzoic acid (2.69 g, 17.3 mmol) in dry THF (20 mL) at 0° C. The mixture was stirred at room temperature for approximately 1 hr and cooled to 0° C. again. Na2SO4. 10H2O (10 g) was added slowly with stirring for 20 minutes. The mixture was filtered, the solid was washed with THF. The solution was concentrated to yield a yellow solid as (2-amino-6-fluoro-phenyl)-methanol (2.49 g). MS [M−OH]+: 124.1; tR=0.57 min.
