As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO110,mainly used in chemical industry, its synthesis route is as follows.,1309774-03-5
0386-2> A mixture of 7-bromo-2-chloro-1,5-naphthyridine (182 mg), bis(pinacolato)diboron (286 mg), (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) dichloride (61 mg), potassium acetate (147 mg), and 1,4-dioxane (4 mL) was stirred at 80 C. for 2 hours in a nitrogen atmosphere. 3-Ethyl-4-iodo-1-(3-(pyrrolidin-1-yl)propyl)-1H-pyrazole (250 mg), sodium carbonate (158 mg), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (53 mg), and water (0.4 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 2-chloro-7-(3-ethyl-1-(3-(pyrrolidin-1-yl)propyl)-1H-pyrazol-4-yl)-1,5-naphthyridine (161 mg). MS m/z (M+H): 370.
With the complex challenges of chemical substances, we look forward to future research findings about 7-Bromo-2-chloro-1,5-naphthyridine,belong naphthyridine compound
