실험 절차
A mixture of 7.0 g (0.04 mole) 3-fluoro-5-bromopyridine, 15.3 g (0.048 mole) tributyl(vinyl)stannane, 2.5 g (0.002 mole) tetrakis(triphenylphosphine)palladium in 70 ml toluene was boiled with reflux during 16 hours. Toluene was evaporated with a 30 cm column. The residue was fractionated twice.
