Reaction Steps

A mixture of tert-butyl 4-(4-(benzyloxy)-3-iodo-2-oxopyridin-1(2H)-yl)piperidine-1-carboxylate (2.4 g), potassium vinyl trifluoroborate (0.945 g), triethylamine (1.3 mL), a dichloromethane adduct of 1,1′-bis(diphenylphosphino)ferrocene-palladium(II) dichloride (0.269 g), and ethanol (47 mL) was stirred overnight at 90 C in a nitrogen atmosphere. After cooling to room temperature, the solvent was distilled off under reduced pressure. Water and ethyl acetate were added to the obtained residue, and the organic layer was separated. The obtained organic layer was washed with saturated saline and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate) to obtain the title compound (1.48 g).
