実験手順

To a solution of 4-bromo-3-tert-butylphenol (Intermediate 104, 1.17 g, 5.10 mmols) and imidazole (520.0 mg, 7.65 mmols) in 10 mL DMF was added chloro-triisopropylsilane (1.18 g, 6.10 mmols). After stirring overnight at room temperature the solution was diluted wirth H2O and extracted with EtOAc. The combined organic layers were washed with H2O and saturated aqueous NaCl before being dried (MgSO4) and concentrated under reduced pressure. The title compound, 1.80 g (92%), was isolated by column chromatography (0-1.5% EtOAc-hexanes) as a colorless oil.
