Reaction Steps

Dissolve 3-bromo-5-methoxypyridine (1.0 g, 5.35 mmol) in diisopropylamine (17 mL) and toluene (10 mL) under nitrogen. Add tetrakis(triphenylphosphine)palladium (0.200 g, 0.16 mmol). Heat at 60° C. and add 1-ethynyl-4-fluorobenzene (642 mg, 5.35 mmol) and copper (I) iodide (20 mg, 0.11 mmol). After 20 h, concentrate, and purify using silica gel chromatography, eluting with 30:70 ethyl acetate:hexanes, to give the title compound (720 mg, 60%).
