Reaktionsschritte

Under nitrogen, a mixture of tert-butyl [(1S)-2-(4-ethynyl-3-fluorophenoxy)-1-methylethyl]carbamate (9.36 g), 2-bromo-5-ethoxypyridine (5.86 g), bis(triphenylphosphine)palladium(II) dichloride (2.04 g), cuprous iodide (0.552 g), triethylamine (6.06 mL), and toluene (20 mL) was stirred at 100° C. overnight. The precipitate was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (7.00 g) as a yellow solid.
