実験手順

To a stirred solution of 2-amino-3-nitro-6-methylpyridine (8.5 g, 55 mmol) in conc. H2SO4 (100 mL) at 0° C. was added HNO3 (2.74 mL, d=1.49, 58.3 mmol) dropwise over 10 min. The mixture was warmed to r.t. for 30 min then heated to 50° C. for 90 min. The reaction mixture was cooled and poured into 200 g of ice. The resulting percipitate was filtered and air dried to give 2-amino-3,5-dinitro-6-methylpyridine as a yellow solid.
