Procedure

Place 3-bromopyridine hydrochloride (0.78 g, 4 mmol), α-(ethynyl)-benzenemethanol (661 mg, 5 mmol) and diethylamine (25mL) under nitrogen atmosphere. Add bis(triphenyl-phosphine)palladium(II) chloride (140mg) then copper(I) iodide (20 mg). Stir overnight at room temperature and filter. Evaporate the solvent in vacuo and filter through silica gel (2:1 ethyl acetate/hexane). Evaporate the solvent in vacuo and recrystallize (25% ethyl acetate/hexane) to yield the title compound.
