Reaktionsschritte

To a stirred solution of 2-amino-3-nitro-4-methylpyridine (25.6 g, 167 mmol) in conc. H2SO4 (100 mL) at 0° C. was added HNO3 (7.77 mL, d=1.49) dropwise over 30 min. The mixture was warmed to r.t. for 20 min then heated to 45° C. for 90 min. The reaction mixture was cooled and poured into 500 g of ice. The resulting percipitate was filtered and air dried to give 2-amino-3,5-dinitropyridine as a yellow solid.
