5-Methyl-5-[4-(1-methylethoxy)phenyl]imidazolidine-2,4-dione (25.8 mg), triphenylphosphine (22.8 mg) and a solution of ethyl azodicarboxylate in toluene (2.2 mol/L, 34.7 μL) were added to a mixed solution of 5-[4-[1,1,1,3,3,3-hexafluoro-2-(methoxymethyl)oxypropan-2-yl]-2-propylphenyloxy]pentan-2-ol (15.0 mg, 34.7 μmol) in tetrahydrofuran (1 mL) at room temperature. After completion of the reaction, the solvent was evaporated, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to obtain 19.0 mg of the title compound (yield: 89%) as a colorless oil.
