الإجراء التجريبي

To the solution of ethanol (77 mg, 1.67 mmol) in perchloromethane (80 mL) was added bismuth(III) bromide (743 mg, 1.67 mmol), the mixture was stirred for 30 minutes at room temperature, the methyl 4-(1-hydroxyethyl)benzoate (300 mg, 1.67 mmol) was added, the mixture was stirred at room temperature for 12 hours. Then the mixture was concentrated and purified by column chromatography (silica gel, Petroleum ether/ethyl acetate=20:1) to give methyl 4-(1-ethoxy ethyl)benzoate (191 mg, 55%) as oil.
