反応手順
Tetrabutylammonium fluoride (0.1 ml of 1M in THF) was added to a solution of 2-furan-2-yl-benzaldehyde (123 mg, 0.71 mmol) and trifluoromethyl trimethylsilane (120 mg, 0.86 mmol) in 10 ml THF at 0° C. The mixture was warmed up to room temperature and stirred for 4 hours. The reaction mixture was then treated with 3 ml of 1M HCl and stirred overnight. The product was extracted with ethyl acetate (3×20 ml). The organic layer was separated and dried over sodium sulfate. The organic solvent was evaporated to give 0.150 g of 2,2,2-trifluoro-1-(2-furan-3-yl-phenyl)-ethanol, which was directly used in next step without purification (yield: 90%).
