Reaction Steps

To a solution of 2-(5-bromo-2-chloropyridin-3-yl)imidazo[1,2-a]pyridine-3-carbaldehyde (100 mg, 0.29 mmol) in MeOH (5 mL), NaBH4 (20 mg, 0.53 mmol) was added at 0° C. The reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was added water and extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. The resulting residue was purified using PTLC (eluted with dichloromethane:MeOH=30:1) to provide (2-(5-bromo-2-chloropyridin-3-yl)imidazo[1,2-a]pyridin-3-yl)methanol (30 mg, yield: 29%). 1H-NMR (DMSO, 400 MHz) δ 8.66 (d, J=2.4 Hz, 1H), 8.49 (d, J=6.8 Hz, 1H), 8.25 (d, J=2.4 Hz, 1H), 7.64 (d, J=9.2 Hz, 1H), 7.35˜7.40 (m, 1H), 7.03˜7.07 (m, 1H), 5.33 (t, J=5.2 Hz, 1H), 4.75 (d, J=5.2 Hz, 2H). MS (M+H)+: 338/340.
