Versuchsvorschrift

A mixture of 2-(1-benzenesulfonyl-1H-indol-5-yl)-2-phenyl-ethanol CCLXVII (1.06 g, 2.707 mmol), tert-butyldimethylchlorosilane (0.45 g, 2.978 mmol) and imidazole (200 mg, 2.978 mmol) in N,N-dimethylformamide (20 mL) was stirred at room temperature for 4 hours. The resulting mixture was diluted with water and extracted with diethyl ether. The organic layer was washed with water and brine, dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure. The crude residue was purified by flash chromatography (EtOAc/hexane, 10/90) to give 1-benzenesulfonyl-5-[2-(tert-butyl-dimethyl-silanyloxy)-1-phenyl-ethyl]-1H-indole CCLXVIII as a yellow oil.
