To a solution of 4-(1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl)-2-propylphenol (500 mg, 1.44 mmol) in N,N-dimethylformamide (7.2 mL), potassium carbonate (300 mg, 2.17 mmol) was added. Under ice-cold conditions, the resultant mixture was added with 5-fluoro-2-nitrobenzaldehyde (220 mg, 1.30 mmol) and stirred at 60° C. for 1 hour. The reaction solution was cooled down to room temperature, added with water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, concentrated in vacuo, and purified using preparative thin-layer chromatography (hexane/ethyl acetate). 5-(4-(1,1,1,3,3,3-Hexafluoro-2-(methoxymethoxy)propan-2-yl)-2-propylphenoxy)-2-nitrobenzaldehyde (576 mg, yield 89%) was obtained as a yellow oil.
