반응 단계
2-(6-chloro-5-methyl-2-(triethylsilyl)-1H-indol-3-yl)ethanol was prepared according to method D Step II with 5-chloro-2-iodo-4-methylaniline (1.50 g; 5.61 mmol), 4-(triethylsilyl)but-3-yn-1-ol (2.36 mL; 11.22 mmol), Bis(diphenylphosphino)ferrocene]palladium(II) chloride (0.229 g; 0.280 mmol), lithium chloride (0.237 g; 5.61 mmol) and sodium carbonate (1.19 g; 11.22 mmol) in DMF (14 mL). The crude material was purified by flash chromatography on silica gel (eluent 2 to 20% ethyl acetate in heptane) to afford 1.44 g (79%) of 2-(6-chloro-5-methyl-2-(triethylsilyl)-1H-indol-3-yl)ethanol as a brown oil.
