Procedure

A mixture of 1-benzenesulfonyl-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (prepared as in Example 3, 4 g, 7.1 mmol) in tetrahydrofuran (5 mL) and a tetrabutylammonium fluoride solution in tetrahydrofuran (1 M, 15 mL, 15 mmol) was stirred at room temperature for 12 h. The 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-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (2.5 g, 83.3%) as a white solid: LC/MS m/e calcd for C23H24N2O4S [M+H]+ 425.52, observed 424.9.
