Reaction Steps

To 11 mL concentrated sulfuric acid was added 2,6-dichloropyridin-4-amine (2.18 g, 13.4 mmol) in an ice bath. After it was cooled to 0° C., 4.4 mL 90% nitric acid was added dropwise. After the reaction was performed by stirring for 1 h at room temperature, the reaction solution was poured into ice water to precipitate a solid product, and subjected to suction filtration. The resultant solid was washed with water and dried to afford 2.28 g titled product with a yield of 81.8%.
