4-Amino-3-iodobenzonitrile (0.10 g; 0.41 mmol), 4-(3-fluorobenzyl)-N-(4-(triethylsilyl)but-3-ynyl)benzamide (0.162 g; 0.41 mmol) bis(diphenylphosphino)ferrocene]palladium(II) chloride (0.017 g; 0.020 mmol), lithium chloride (0.017 mg; 0.410 mmol) and sodium carbonate (0.087 g; 0.820 mmol) were suspended in DMF (5 mL) and the mixture was stirred at 100° C. for 15 hours. The solution was concentrated under reduced pressure and diluted in ethyl acetate. The organic layer was successively washed with brine, sodium thiosulfate, dried and concentrated under reduced pressure. The crude residue was purified by flash chromatography on silica gel (eluent 2 to 60% ethyl acetate in heptane) to afford 0.056 g (27%) of the title compound as a white solid.
