Procedure

According to Reference Example 8-12, by use of 3-fluorobenzaldehyde (500 mg, 4.03 mmol), (trifluoromethyl)trimethylsilane (715 μL, 4.83 mmol), tetrabutylammonium fluoride (a 1.0 mol/L solution in tetrahydrofuran, 403 μL, 0.403 mmol) and tetrahydrofuran (10 mL), the mixture was stirred and reacted at room temperature for 3 hours. Thus, 1-fluoro-3-(2,2,2-trifluoro-1-hydroxyethyl)benzene (Compound DA) (942 mg, yield: quantitative) was obtained.
