15 g of 4-nitrophenylethanol, 28.1 g of triphenylphosphine and 9.2 g of imidazole are dissolved in 500 ml of THF, mixed in portions with 27.77 g of iodine and stirred for 2 hours at room temperature. The reaction mixture is mixed with ammonium chloride solution and extracted with dichloromethane. The organic phase is washed in succession with sodium thiosulfate solution and water and dried on sodium sulfate. After purification by chromatography on silica gel, 23.22 g of the title compound is obtained.
