실험 절차

Sodium hydride (purity: 50%) (38.9 mg, 0.81 mmol) was added to a mixed solution of 2-(4-benzyloxy-3-propylphenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (264.0 mg, 0.67 mmol) in tetrahydrofuran (5 mL) under ice-cooling. Then, chloromethyl methyl ether (65.0 mg, 0.81 mmol) was added, followed by stirring overnight. Water was added to the reaction solution, followed by extraction with ethyl acetate. Then, the organic layer was washed with saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel preparative thin-layer chromatography (hexane:ethyl acetate=10:1) to obtain 264.9 mg of the title compound (yield: 90%) as a pale yellow oil.
