4-Nitrophenol (0.36 g, 2.56 mmole), 5-(chloromethyl)-3-phenyl-1,2,4-oxadiazole (0.5 g, 2.56 mmole) and anhydrous K2CO3 (0.39 g, 2.82 mmole) were dissolved in anhydrous acetone (20 mL) and heated to reflux for 12 h. Reaction mixture was cooled and the solvent removed under vacuum. The crude solid formed was collected by filtration, washed with water and dried under vacuum to provide 5-[(4-nitrophenoxy)methyl]-3-phenyl-1,2,4-oxadiazole (0.70 g, 92%). 1H NMR (CDCl3): δ 8.25 (d, 2H, J=8.8 Hz), 8.08 (dd, 2H, J=8.2 Hz), 7.52-7.49 (m, 3H), 7.13 (d, 2H, J=8.8 Hz), 5.45 (s, 2H).
