Reaktionsschritte
Tetrabutylammonium fluoride (0.024 ml; 1.0 M solution in tetrahydrofuran) was added to a solution of 4-furan-3-yl-benzaldehyde (410 mg, 2.38 mmol) and trifluoromethyltrimethylsilane (TMSCF3) (423 μl, 2.86 mmol) in 5 ml THF at 0° C. The formed mixture was warmed up to room temperature and stirred at room temperature for 4 hours. The reaction mixture was then treated with 5 ml of 1N HCl and stirred at room temperature overnight. The product was extracted with ethyl acetate (3×50 ml). The organic layer was separated and dried over sodium sulfate. The organic solvent was evaporated to give 480 mg of 2,2,2-trifluoro-1-(4-furan-3-yl-phenyl)-ethanol, yield: 83%.
