Reaction Steps

To a stirring ice-cooled mixture of 5.0 g of 4-hydroxy-2-methoxybenzaldehyde, 4.5 g of 2-(2-pyridyl)ethanol and 10.3 g of triphenylphosphine was added dropwise 15.8 g of a 40% solution of diethyl azodicarboxylate in toluene. The mixture was stirred at room temperature for 5 hours. The reaction mixture was concentrated, purified by silica gel column chromatography (hexane/acetone system) and further purified by silica gel column chromatography (hexane/AcOEt system) to give 5.84 g of the title compound (69% yield).
