As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO378,mainly used in chemical industry, its synthesis route is as follows.,1569-16-0
To a solution of (R)-tert-butyl 3-(1,1-difluoro-4-iodobutyl)pyrrolidine-1-carboxylate (700 mg, 1.88 mmol) and 2-methyl-1,8-naphthyridine (407 mg, 2.82 mmol) in THF (12 mL) at 0¡ã C. was added LiHMDS (2.82 mL, 1M, 2.82 mmol). The reaction mixture was stirred at 0¡ã C. for 3 h, then quenched with saturated ammonium chloride solution (6 mL), diluted with water (15 mL) and extracted with EtOAc (30 mL¡Á2). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by prep-TLC to give the desired product tert-butyl 3-(5-(1,8-naphthyridin-2-yl)pentyl)-3-fluoropyrrolidine-1-carboxylate as a light yellow solid (350 mg). Yield 48percent (ESI 388 (M+H)+).
With the synthetic route has been constantly updated, we look forward to future research findings about 2-Methyl[1,8]-Naphthyridine,belong naphthyridine compound
