반응 단계
To a room temperature solution of 100 mg (0.23 mmol) of 2,2,2-trifluoro-1-[1-(4-fluorophenyl)-1H-indazol-5-yl]-1-(1H-indol-3-yl)ethanol in THF was added 20.0 mg (0.50 mmol) of 60% NaH in mineral oil. After hydrogen evolution ceased, 14.5 mg (0.25 mmol) of (R)-(+)-propylene oxide was added. The reaction was then warmed at 60° C. for 5 hours. The reaction was then cooled to room temperature and diluted with water and extracted with ether. The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash chromatography (20-40% ethyl acetate in hexanes). The major fractions were combined and concentrated to provide 53 mg (46.6%) of the title compound. MS m/z 484.47 (MH+).
