To a solution of 4-(1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl)-2-propylphenol (1.68 g, 4.86 mmol) in N,N-dimethylformamide (30 mL), potassium carbonate (1.34 g) and methyl 2-chloro-5-nitroisonicotinate (1.58 g) were added, and the resultant mixture was stirred in an oil bath with the oil temperature at 80° C. After completion of the reaction, the reaction solution was neutralized by adding 2 mol/L of hydrochloric acid, added with water, and extracted with ethyl acetate. Subsequently, the organic layer was washed with brine, dried using anhydrous sodium sulfate, and concentrated in vacuo. The residue was purified using thin-layer silica-gel column chromatography (hexane/ethyl acetate) and the title compound (1.86 g, yield 73%) was obtained as a colorless oil.
