With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1309774-03-5,7-Bromo-2-chloro-1,5-naphthyridine,as a common compound, the synthetic route is as follows.
0390-7 A mixture of 7-bromo-2-chloro-1,5-naphthyridine (29 mg), bis(pinacolato)diboron (36 mg), (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) dichloride (10 mg), potassium acetate (23 mg), and 1,4-dioxane (1 mL) was stirred at 80 C. for 2 hours in a nitrogen atmosphere. 4-(3-(4-iodo-3-propyl-1H-pyrazol-1-yl)propyl)morpholine (43 mg), sodium carbonate (25 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (8 mg), and water (0.1 mL) were added thereto, followed by stirring at 80 C. for 3 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-propyl-1H-pyrazol-1-yl)propyl)morpholine (11 mg). MS m/z (M+H): 400.
1309774-03-5, As the paragraph descriping shows that 1309774-03-5 is playing an increasingly important role.
