実験手順

To a solution of methyl (E)-3-(5-(1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl)-3-(prop-1-enyl)pyridin-2-yloxy)benzoate (81 mg, 0.168 mmol) in tetrahydrofuran (2 mL), lithium aluminum hydride (9.6 mg, 0.252 mmol) was added under ice-cold conditions, and the resultant mixture was stirred at room temperature for 3 hours. The reaction solution was added with methanol and water, filtered using celite, and extracted with ethyl acetate. The organic layer was washed with brine, dried using anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified using silica-gel column chromatography (ethyl acetate), and the title compound (72 mg, yield 94.9%) was obtained as a yellow oil.
