(2-Chloro-5-(4-(1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl)-2-propylphenoxy) phenyl)methanol (10 mg, 0.0212 mmol), 5-methyl-5-(4-(1-methylethoxy)phenyl)imidazolidine-2,4-dione (16 mg, 0.0635 mmol) and triphenylphosphine (16 mg, 0.0635 mmol) were added and dried in vacuo. N, N-dimethylformamide (300 μL) was added, and under ice-cold conditions, a solution of diethyl azodicarboxylate in tetrahydrofuran (29 μL, 0.0635 mmol) was added. The resultant mixture was stirred at room temperature for 4 hours. The reaction solution was 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). 3-(2-Chloro-5-(4-(1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl)-2-propylphenoxy) benzyl)-5-(4-(1-methylethoxy)phenyl)-5-methylimidazolidine-2,4-dione (7.6 mg, yield >100%) was obtained as a yellow oil.
