Reaction Steps

Tetrabutylammonium fluoride (TBAF) (0.1 ml of 1M in THF) was added to a solution of 4-(6-methoxy-pyridine-2-yl)-benzaldehyde (213 mg, 1 mmol) and trifluoromethyl trimethylsilane (0.2 ml, 1.2 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 12 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 0.25 g of 1-[4-(6-methoxy-pyridine-2-yl)-phenyl]-2,2,2-trifluoro-ethanol which was directly used in next step without purification. yield: 90%.
