実験手順
575 mg (0.89 mmol) of {4-(benzyloxy)-3-[(4-fluorophenyl)sulphonyl]phenyl}{2,6-dimethyl-4-[(triisopropylsilyl)oxy]phenyl}methanol (Example VIII) are dissolved in 10 ml of tetrahydrofuran. At 0° C., 1030.35 mg (8.86 mmol) of triethylsilane are initially added, and 78.78 mg (0.35 mmol) of trimethylsilyl trifluoromethane-sulphonate are then added dropwise. The reaction mixture is stirred for 1.5 hours, and saturated ammonium chloride solution is then added. The mixture is extracted three times with ethyl acetate, the combined organic phases are dried over sodium sulphate and the solvent is removed under reduced pressure. This gives 611 mg (53% of theory) of (4-{4-(benzyloxy)-3-[(4-fluorophenyl)sulphonyl]benzyl}-3,5-dimethylphenoxy)(triisopropyl)silane.
