1309774-03-5, 7-Bromo-2-chloro-1,5-naphthyridine is a naphthyridine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
0375-2 1,4-Dioxane (2 mL)/water (0.2 mL) was added to a mixture of 7-bromo-2-chloro-1,5-naphthyridine (75 mg), 2-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)methyl)pyridine (105 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (21 mg), and sodium carbonate (65 mg), followed by stirring at 100 C. for 2 hours. After the reaction mixture was cooled to room temperature, the insolubles were filtered off using celite, and the filter cake was washed with ethyl acetate. The filtrate and the washings were combined, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate-hexane, methanol-ethyl acetate, NH silica), thereby obtaining 2-chloro-7-(1-(pyridin-2-ylmethyl)-1H-pyrazol-4-yl)-1,5-naphthyridine (64 mg) as a yellow solid. MS m/z (M+H): 322.
1309774-03-5, The synthetic route of 1309774-03-5 has been constantly updated, and we look forward to future research findings.
