Procedure

4-Chloro-3-phenylpyridine (200 mg, 1.06 mM), paranitrophenol (440 mg, 3.18 mM), Hunig's base (isoPr2EtN, diisopropylethylamine, 1 ml) and 1-methylpyrrolidone (2 ml) were stirred at 160° C. for 2 hours. Water was added, extraction was performed with ethyl acetate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography (hexane:ethyl acetate=4:1, and then 2:1) to obtain 4-(4-nitrophenoxy)-3-phenylpyridine (150 mg) as a light yellow oil.
