Reaction Steps

To a solution of the 4-(2-fluoro-4-nitro-phenoxy)-6-methoxy-7-hydroxyquinoline (609 mg, 1.8 mmol) in DMF (9 mL) was added K2CO3 (1.24 g, 9.0 mmol) and N-Boc-4-piperidinemethanol mesylate (732 mg, 2.5 mmol). The mixture was then stirred at 80° C. for 2.5 h. After it was cooled to rt, the mixture was loaded directly to a Biotage column, and eluted with solvents (hexanes:EtOAc=1:3). The resulting product, 4-[4-(2-fluoro-4-nitro-phenoxy)-6-methoxy-quinolin-7-yloxymethyl]-piperidine-1-carboxylic acid tert-butyl ester, was obtained as a solid (556 mg, 56%).
