실험 절차

Potassium carbonate (722 mg, 5.23 mmol) was added to a solution of 1-benzenesulfonyl-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-ol (prepared as in Example 13, 900 mg, 1.72 mmol) in N,N-dimethylformamide (2 mL) at room temperature. The mixture was stirred for 30 min and then treated with (2-bromo-ethoxy)-tert-butyl-diphenyl-silane (658 mg, 1.81 mmol) at room temperature. The mixture was heated at 80° C. and stirred for 3 h. The resulting mixture was diluted with ethyl acetate (150 mL), washed with brine, dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by flash silica gel chromatography (silica gel from QingDao, 200-300 mesh, glass column from Shanghai SD company, 33% ethyl acetate/hexanes) afforded 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, 62.8%) as a white solid.
