실험 절차

To a degassed solution of 3-bromo-4-cyclopropylmethoxybenzaldehyde (1.53 g, 6 mmol), 4-methoxybenzeneboronic acid (1.22 g, 8 mmol) and potassium carbonate (2.74 g, 20 mmol) in toluene/ethanol 2/1 (40 mL), Pd(PPh3)4 (100 mg) was added and the mixture was degassed for further 5 minutes. The mixture was then refluxed for 12 hours. The solid is filtered off, and the solvent partitioned between ethyl acetate and water and extracted. The organic solvent was removed under reduced pressure, dried over sodium sulphate and purified by column chromatography on silica (hexane/ethyl acetate 8/2) to afford 1.52 g of product.
