Reaction Steps

4-Methyl-5-nitro-2-pyridinamine (3.69 g, 2.41 mmol) was added with acetic anhydride (10 ml) and stirred at 130° C. for 1.5 hours. The reaction mixture was left stand for cooling, and then added with distilled water (5.4 ml) at 0° C., heated to 130° C., and stirred for 45 minutes. The reaction mixture was left stand for cooling and concentrated, and the deposited crystals were collected by filtration and washed with distilled water to obtain the title compound (4.71 g, quantitative).
