Yield	Reaction Conditions	Operation in experiment
91%		Reference Example 53 3-[2,4-bis(trifluoromethyl)benzyl]oxy}-2-methoxybenzaldehyde; [Show Image] To a solution (16 mL) of <strong>[66495-88-3]3-hydroxy-2-methoxybenzaldehyde</strong> (1.00 g) in N,N-dimethylformamide was added potassium carbonate (1.37 g), and the mixture was stirred at room temperature for 0.5 hr. To the reaction mixture was added a solution (2 mL) of 1-(bromomethyl)-2,4-bis(trifluoromethyl)benzene (2.29 g) in N,N-dimethylformamide, and the mixture was stirred at room temperature for 3 days. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=100:0→90:10) to give the title compound as a pale-yellow oil (yield: 2.27 g, 91%). 1H-NMR (DMSO-d6, 300 MHz):δ3.92 (3H, s), 5.44 (2H, s), 7.20-7.29 (1H, m), 7.36 (1H, dd, J = 7.9, 1.6 Hz), 7.49 (1H, dd, J = 8.0, 1.6 Hz), 8.10 (1H, d, J = 8.3 Hz), 8.14 (1H, s), 8.20 (1H, d, J = 8.3 Hz), 10.32 (1H, s).
