To a suspension of 4,5-Dichloro-2-{4-[2-(3-chloro-phenylamino)-pyrimidin-4-yl]-pyridin-2-yl}-2H-pyridazin-3-one (0.3 g) in acetonitrile (10 mL) was added of 0.09 g of sodium azide. The mixture was heated to reflux for 4 h. The suspension was filtered to give the title compound as a solid (0.280 g, 95%). Mp 184–186° C., 1H NMR (DMSO-d6) 10.1 (1H, s, NH), 8.75 (1H, d, 6 Hz), 8.67 (1H, d, 3 Hz), 8.28 (1H, s), 8.27 (1H, s), 8.18(1H, dd, 1 Hz, 3 Hz), 7.97 (1H, m), 7.65 (1H, dd), 7.57(1H, d, 6 Hz), 7.25 (1H, t, 9 Hz), 6.94 (1H, dd).
