Reaction Steps
To a solution of methyl 2-(1-hydroxyethyl)-1-benzofuran-6-carboxylate (1.10 g, 4.99 mmol) in toluene (20 mL) were added diphenyl azidophosphate (1.62 mL, 7.50 mmol) and DBU (1.50 mL, 9.98 mmol), and the mixture was stirred at room temperature for 2.5 hr. Ethyl acetate was added thereto, and the mixture was washed with water, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=20:1 to 2:3) to give the title compound (1.22 g, yield 88%) as an oil.
