Yield: 96.6%
Reaction Conditions:
with N-Bromosuccinimide in dichloromethane at 25; for 4 h;
Steps:
A Step A.3-Bromo-2-methoxypyridin-4-amine.
To a solution of 2-methoxypyridin-4-amine (5.0 g, 40.28 mmol) in DCM (10 mL) was added NBS (7.17 g, 40.28 mmol) at 0°C. Then the reaction mixture was stirred at 25°C for 4 hrs. The solvent was removed under reduced pressure. The residue was purified by column chromatography (SiO2, Petroleum ether/EtOAc=5/1 to 2/1) to give the title compound (7.9 g, 38.91 mmol, 96.60% yield) as a yellow oil.1H NMR (400 MHz, CDCl3) d = 7.67 (d, J = 5.6 Hz, 1H), 6.26 (d, J = 5.6 Hz, 1H), 3.90 (s, 3H).
