실험 절차

A solution of 1-benzenesulfonyl-5-[2-(tert-butyl-diphenyl-silanyloxy)-ethoxy]-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (870 mg, 1.08 mmol) in tetrahydrofuran (0.5 mL) and a tetrabutylammonium fluoride solution in tetrahydrofuran (1 M, 10 mL, 10 mmol) was stirred at room temperature for 12 h. The resulting mixture was diluted with ethyl acetate (150 mL), washed with a saturated aqueous ammonium chloride solution and brine, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 2-{2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-yloxy}-ethanol (460 mg, quant.) as a white solid: LC/MS m/e calcd for C23H26N2O4S [M+H]+ 427.54, observed 427.4.
