Reaction Steps

Under argon atmosphere, ethynyl(trimethyl)silane (9.0 ml) was mixed with triethylamine (50 ml), and (3-bromo-2-fluorophenyl)methanol, bis(triphenylphosphine)palladium chloride (II) (1.54 g), and copper iodide (420 mg) were added thereto, followed by stirring at 90° C. overnight. The reaction mixture was cooled to room temperature, and EtOAc was added thereto, followed by filtering using Celite as a filtration adjuvant. The filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain {2-fluoro-3-[(trimethylsilyl)ethynyl]phenyl}methanol (4.88 g).
