실험 절차

A mixture of 4-chloro-2-fluoro-6-iodoaniline (0.100 g; 0.368 mmol), 5-(2,5-difluorobenzyl)-N-(4-(triethylsilyl)but-3-ynyl)isoxazole-3-carboxamide (0.150 g; 0.347 mmol), Bis(diphenylphosphino)ferrocene]palladium(II) chloride (0.015 g; 0.018 mmol), lithium chloride (0.016 mg; 0.368 mmol), sodium carbonate (0.078 g; 0.737 mmol) in DMF (5 mL) was stirred at 100° C. overnight. The solution was reparted between ethyl acetate and brine, washed with sodium thiosulphate, dried and concentrated under reduced pressure. The crude mixture was purified by flash chromatography on silica (eluent 2 to 60% ethyl acetate in heptane) to yield 0.05 g (25%) of N-(2-(5-chloro-7-fluoro-2-(triethylsilyl)-1H-indol-3-yl)ethyl)-5-(2,5-difluorobenzyl)isoxazole-3-carboxamide as a yellow oil.
