Extracurricular laboratory: Synthetic route of C5H8N2

The synthetic route of 930-62-1 has been constantly updated, and we look forward to future research findings.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 930-62-1, name is 2,4-Dimethylimidazole, A new synthetic method of this compound is introduced below., Computed Properties of C5H8N2

Example 0698 A mixture of tris(dibenzylideneacetone)dipalladium(0) (27 mg), 2-di-tert-butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropyl-1,1′-biphenyl (29 mg), tripotassium phosphate (96 mg), and toluene (1.5 mL) was stirred at 110 C. for 5 minutes in a nitrogen atmosphere. 7-Bromo-N-(5-isopropylpyridazin-3-yl)-1,5-naphthyridine-2-amine (50 mg) and 2,4-dimethyl-1H-imidazole (43 mg) were added to the reaction mixture, followed by stirring at 110 C. for 4 hours. The reaction mixture was cooled to room temperature, and the solvent was distilled off under reduced pressure. The obtained residue was purified sequentially by silica gel column chromatography (hexane-ethyl acetate-methanol), preparative thin layer silica gel column chromatography (chloroform-methanol, NH silica), and preparative thin layer silica gel column chromatography (chloroform-methanol), thereby obtaining 7-(2,4-dimethyl-1H-imidazol-1-yl)-N-(5-isopropylpyridazin-3-yl)-1,5-naphthyridine-2-amine (10 mg) as a pale yellow solid. 1H-NMR (DMSO-d6) delta: 10.87 (1H, s), 8.87 (1H, d, J=1.8 Hz), 8.82 (1H, d, J=1.8 Hz), 8.33 (1H, d, J=9.0 Hz), 8.31 (1H, brs), 8.22 (1H, brs), 7.82 (1H, d, J=9.0 Hz), 7.21 (1H, s), 3.10-2.95 (1H, m), 2.34 (3H, s), 2.08 (3H, s), 1.30 (6H, d, J=6.6 Hz). MS m/z (M+H): 360.

The synthetic route of 930-62-1 has been constantly updated, and we look forward to future research findings.
