実験手順

A mixture of N-(5-chloro-7-(5-fluoro-2-methylphenyl)-2,6-naphthyridin-3-yl)cyclopropanecarboxamide (50 mg, 0.14 mmol), palladium acetate (2 mg, 0.007 mmol), 1,3-bis(dicyclohexylphosphino)propane bis(tetrafluoroborate) (9 mg, 0.014 mmol), potassium carbonate (29 mg, 0.21 mmol), methanol (0.1 mL), and N,N-dimethylformamide (1 mL) was purged with nitrogen and evacuated (3×), flushed with carbon monoxide and evacuated (2×), and then left under a carbon monoxide balloon and heated at 100° C. for 2 hours. The cooled reaction mixture was diluted with ethyl acetate (50 mL) and washed with water (100 mL). The organic layer was separated, dried over sodium sulfate, filtered, and evaporated in vacuo to afford a residue that was purified by flash chromatography (silica, 4 g, ISCO, 0-50% ethyl acetate in heptane) to afford the title compound as a pale yellow solid (50 mg, 90%), which was used in the next step without further purification.
