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
0385-7 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (142 mg), bis(pinacolato)diboron (223 mg), (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) dichloride (47 mg), potassium acetate (115 mg), and 1,4-dioxane (3 mL) was stirred at 80 C. for 2 hours in a nitrogen atmosphere. 4-(3-(3-ethyl-4-iodo-1H-pyrazol-1-yl)propyl)morpholine (204 mg), sodium carbonate (124 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (41 mg), and water (0.3 mL) were added thereto, followed by stirring at 80 C. for 4 hours. The reaction mixture was cooled to room temperature, the insolubles were filtered off using celite, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (methanol-ethyl acetate, NH silica), thereby obtaining 4-(3-(4-(6-chloro-1,5-naphthyridin-3-yl)-3-ethyl-1H-pyrazol-1-yl)propyl)morpholine (18 mg). MS m/z (M+H): 386., 1309774-03-5
As the paragraph descriping shows that 1309774-03-5 is playing an increasingly important role.
