実験手順
Add triethylamine (6.2 mL, 44 mmol), copper (I) iodide (120.3 mg, 1.10 mmol) and bis(triphenylphosphine)palladium (II) dichloride (386 mg, 0.55 mmol) to a solution of 3-bromo-5-ethynylpyridine, (prepared essentially as described in PREPARATION 23), (2.0 g, 11 mmol) and 1-iodo-3-trifluoromethylbenzene (1.53 mL, 11 mmol) in ethyl acetate (12 mL). Stir at room temperature for 18 h. Concentrate and purify the residue by silica gel chromatography, eluting with 100:0 to 100:50 hexanes:ethyl acetate to give the title compound (2.1 g, 61%).
