Reaction Steps

A solution of 5-bromo-2-chloro-3-cyano-6-(N,N-dimethylamino)-4-methylpyridine (1.3 g) in concentrated sulfuric acid (3 mL) was heated at 120° C. for 10 minutes. The mixture was cooled, diluted with water (50 mL), and neutralized with saturated sodium carbonate. After extraction with methylene chloride, evaporation of the organic phase gave 1.37 g of the title compound, suitable for use in the next reaction.
