144294-43-9, 3-Amino-5-methylpyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
0388-1 A mixture of 6-chloro-N-(pyrimidin-5-yl)-1,5-naphthyridine-3-amine (10 mg), 5-methylpyridazine-3-amine (6.4 mg), tris(dibenzylideneacetone)dipalladium(0) (3.5 mg), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (4.5 mg), cesium carbonate (25 mg), and 1,4-dioxane (1 mL) was stirred at 140 C. for 30 minutes using a microwave reaction apparatus. The reaction mixture was cooled to room temperature, and the solid matter was collected by filtration, thereby obtaining N2-(5-methylpyridazin-3-yl)-N7-(pyrimidin-5-yl)-1,5-naphthyridine-2,7-diamine (1.6 mg). 1H-NMR(CDCl3/CD3OD=4/1) delta: 8.81 (1H, s), 8.75 (2H, s), 8.73 (1H, brs), 8.64 (1H, brs), 8.51 (1H, d, J=2.4 Hz), 8.12 (1H, d, J=9.0 Hz), 7.83 (1H, d, J=2.4 Hz), 7.36 (1H, d, J=9.0 Hz), 2.45 (3H, s). MS m/z (M+H): 331.
144294-43-9, The synthetic route of 144294-43-9 has been constantly updated, and we look forward to future research findings.
