반응 단계
To a solution of triphenylphosphine (1.56 g, 5.95 mmol) in THF (40 mL) was added DBAD (1.37 g, 5.95 mmol). After 10 min, 4-trifluoromethylphenol (0.964 g, 5.95 mmol) was added. After 10 additional minutes, compound 21A (0.500 g, 3.97 mmol) was added. After 14 h at 25° C., the reaction was concentrated in vacuo and purified by flash chromatography on silica eluting with chloroform to give 0.713 g (44%) of compound 232A as a clear oil.
