실험 절차

According to Reference Example 8-12, by use of 3-chlorobenzaldehyde (500 mg, 3.56 mmol), (trifluoromethyl)trimethylsilane (631 μL, 4.27 mmol), tetrabutylammonium fluoride (a 1.0 mol/L solution in tetrahydrofuran, 360 μL, 0.360 mmol) and tetrahydrofuran (10 mL), the mixture was stirred and reacted at room temperature for 3 hours. Thus, 1-chloro-3-(2,2,2-trifluoro-1-hydroxyethyl)benzene (Compound DB) (1.02 g, yield: quantitative) was obtained.
