실험 절차

To 5-[(1-benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-hydroxy-methyl]-4-chloro-thiazol-2-yl-carbamic acid tert-butyl ester (27, 0.200 g, 0.32 mmol) in 15.0 mL of dichloromethane, triethylsilane (0.600 mL, 376 mmol) and trifluoroacetic acid (0.300 mL, 3.89 mmol) were added. The reaction was stirred at room temperature for 3 hours, then concentrated, poured into aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with 25-100% ethyl acetate in hexane to give the desired compound (28, 0.155 g, 88.7%). MS (ESI) [M+H+]+=538.9.
