With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.929252-65-3,tert-Butyl 4-(((4-(4-amino-2-fluorophenoxy)-6-methoxyquinolin-7-yl)oxy)methyl)piperidine-1-carboxylate,as a common compound, the synthetic route is as follows.,929252-65-3
Step I: Preparation of tert-butyl 4-[[4-[2-fluoro-4-[[1-[(4-fluorophenyl)amino carbonyl]cyclopropanecarbonyl]amino]phenoxy]-6-methoxy-7-quinolyl]oxymethyl]piperidine-1-carboxylate: A mixture of Intermediate C (1.5 g, 3.0 mmol), Intermediate D (1.7 g, 7.6 mmol), DIPEA (1.55 g, 12.0 mmol), HATU (2.3 g, 6.0 mmol), DMAP (0.183 g, 1.5 mmol) in 60 mL of DMF was stirred at 30-40 C. overnight, then concentrated under reduced pressure. The residue was purified by column chromatography (eluted with 1-5% MeOH in DCM) to afford the target product (1.9 g, yield: 90%). The characterization of the resulting product was as follows: Mass spectrum m/z: 703.30 [M+H].
929252-65-3 tert-Butyl 4-(((4-(4-amino-2-fluorophenoxy)-6-methoxyquinolin-7-yl)oxy)methyl)piperidine-1-carboxylate 59342474, apiperidines compound, is more and more widely used in various fields.
