Versuchsvorschrift

8.5 g of this mixture of 2-amino-6-methyl-3-nitropyridine and 2-amino-6-methyl-5-nitropyridine was dissolved in H2SO4 (100 mL) at 0° C. and HNO3 (2.74 mL, d=1.49) was added drop-wise over 10 min. After complete addition, the mixture was warmed to 50° C. for 90 min., cooled, then poured onto 200 g of ice. The residue was collected by filtration and washed with cold H2O (2×50 mL) to give 2-amino-6-methyl-3,5-dinitropyridine as a yellow solid.
