Reaction Steps

To a solution of 3-(benzyloxy)-6-bromo-N-(4-fluorobenzyl)picolinamide (50 mg, 0.11 mmol) in CH2Cl2 (5 mL) was added BBr3 (1.5 mL) dropwise at −78° C. under N2. The mixture was allowed to room temperature and stirred for another 12 hours. Then CH3OH was added and the mixture was adjusted to pH=7 by saturated K2CO3. The mixture was extracted with EtOAc and the combined organic phase was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by prep-TLC (PE:EtOAc=5:1) to afford the product of 6-bromo-N-(4-fluorobenzyl)-3-hydroxypicolinamide (20 mg, yield: 57%). 1H-NMR (CDCl3, 400 MHz) δ 12.04 (s, 1H), 8.02 (s, 1H), 7.39 (d, J=8.8 Hz, 1H), 7.24˜7.28 (m, 2H), 7.15 (d, J=8.8 Hz, 1H), 6.96˜7.00 (m, 2H), 4.52 (d, J=6.4 Hz, 2H). MS (M+H)+: 325/327.
