Reaktionsschritte

15.6 g of diethylaminosulfurtrifluoride (DAST, 96.91 mmol) were dissolved in 18 ml of dichloromethane. At 0-5° C., 12 g of 3-phenyl-1-propanol (88.1 mmol) dissolved in 30 ml of dichloromethane, were added dropwise. The reaction mixture was stirred for 18 h, and, after addition of 30 ml of dichloromethane, poured onto 100 ml of ice water. The organic layer was separated, dried over magnesium sulfate, filtered, and the solvent evaporated. The crude product was purified by distillation at a bath temperature of 106° C. at 20 mm to yield 7.4 g of the title compound.
