2,9-Dimethyl-1,10-phenanthroline (h) (20 g) was dissolved in a mixture of sulfuric acid (120 ml) and nitric acid (40 ml), and the mixture was heated at 100° C. for 12 hours with stirring. The resulting solution was poured into ice water (300 ml), and the formed precipitate was collected. The precipitate was dissolved in water (500 ml) and neutralized with sodium hydroxide. The resulting precipitate was collected and recrystallized from methanol (300 ml) to give the desired 5-nitro-2,9-dimethyl-1,10-phenanthroline (i) (yield=8.8 g).
