General procedure for the synthesis of 2-amino-5-nitro-6-methylpyridine from 2-amino-6-methylpyridine: 10 mL of concentrated sulfuric acid was cooled to 0-1 °C and 2-amino-6-methylpyridine (20 g) was slowly added, keeping the temperature at 0 °C. Subsequently, 110 mL of nitric acid in the ratio of 1:1 by volume was slowly added, stirred at -1 °C and continued stirring at room temperature for 30 min. The reaction mixture was warmed up to 50 °C for 11 hours. After completion of the reaction, the reaction solution was extracted with ethyl acetate (EA). The ethyl acetate layer was washed with ammonia and then the ammonia layer was concentrated. Eventually, the solid product 2-amino-5-nitro-6-methylpyridine (18 g) was precipitated in 75% yield. | [References]
