A) 3-bromo-2-chloropyridine (4.76 g) was dissolved in N,N-dimethylformamide (DMF, 30 mL) under argon protection. Subsequently, a methanolic solution of 28% sodium methanol (5.73 g) was added to this solution. The reaction mixture was stirred at 80°C for 30 minutes. After completion of the reaction, the mixture was cooled to room temperature and the reaction was quenched by the addition of water. The reaction mixture was extracted with ethyl acetate and the organic phases were combined. The organic phase was washed sequentially with water and saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was removed by concentration under reduced pressure to give the crude product 3-bromo-2-methoxypyridine (4.43 g) as a light yellow oil.
