반응 단계

To a solution of 3-amino-2-bromo-6-methoxypyridine (2.7 g) in methylene chloride (20 ml) and pyridine (1 ml) was added 2-chloronicotinoyl chloride (2.2 g), and the resulting mixture was stirred 20 min. The mixture was then diluted with methylene chloride (100 ml), washed with water (100 ml), dried (anhydrous magnesium sulfate), and concentrated. The semisolid residue was saturated with hexane, filtered, and dried to give 4.1 g of product suitable for use in the next reaction.
