실험 절차

According to Reference Example 8-2, by use of 4-(trifluoromethyl)benzaldehyde (100 μL, 0.732 mmol), potassium carbonate (20.2 mg, 0.146 mmol), (trifluoromethyl)trimethylsilane (162 μL, 1.10 mmol) and N,N-dimethylformamide (2.0 mL), the mixture was stirred and reacted at room temperature for 1 hour. Then, purification by silica gel column chromatography (chloroform/methanol=9/1) was performed to give 1-(trifluoromethyl)-4-(2,2,2-trifluoro-1-hydroxyethyl)-benzene (Compound CF) (102 mg, yield: 57%).
