Versuchsvorschrift

5-[4-(1-Methylethoxy)phenyl]-5-methylimidazolidine-2,4-dione (7.7 mg, 0.0311 mmol) was dissolved in N,N-dimethylformamide (500 μL), added potassium carbonate (8.6 mg, 0.0622 mmol) under ice-cold conditions, and the mixture was stirred at room temperature for 5 minutes. Then, under ice-cold conditions, (R,Z)-2-bromo-1-(4-{4-[1,1,1,3,3,3-hexafluoro-2-(methoxymethoxy)propan-2-yl]-2-(prop-1-en-1-yl)phenyl}-3-methylpiperazin-1-yl)ethanone (17 mg, 0.0311 mmol) was added, and stirred at room temperature for 18 hours. Under ice-cold conditions, the reaction solution was added water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained crude product was dissolved in ethyl acetate (1.0 mL), added a solution of 4N-hydrochloric acid-ethyl acetate (1.0 mg), and stirred at room temperature for 1 hour. Under ice-cold conditions, the reaction solution was added water and a saturated aqueous solution of sodium hydrogen carbonate, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and (R,Z)-3-(2-{4-[4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)-2-(prop-1-en-1-yl)phenyl]-3-methylpiperazin-1-yl}-2-oxoethyl)-5-[4-(1-methylethoxy)phenyl]-5-methylimidazolidine-2,4-dione (17.4 mg (yield 83%)) was obtained as a yellow oil.
