実験手順

A solution of tert-butyl [(1S)-2-(3-bromo-4-iodophenyl)-1-(5-phenyl-1H-imidazol-2-yl)ethyl]carbamate (950 mg, 836 μmol), [β-(trimethylsilyl)ethoxy]methyl chloride (163 μL, 919 μmol), N,N-diisopropylethylamine (582 μL) and methylene chloride (8.91 mL) was stirred at 0° C. for 60 min and stirred at 25° C. for 2 h. The reaction was diluted with water and extracted with ethyl acetate three times, dried with sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash column chromatography to yield the desired product (432 mg, 59%). MF=C28H37BrIN3O3Si; LCMS found for C28H38BrIN3O3Si (M+H)+: m/z=698.
