Procedure
To a solution of 1-{4-[1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl]-phenyl}-ethanone (210 mg, 0.43 mmol) in anhydrous tetrahydrofuran (5 mL) at 0° C. was added methylmagnesium chloride in tetrahydrofuran (3 M, 0.43 ml, 1.29 mmol) dropwise. After stirring for 2 h at 0° C., the reaction mixture was poured into brine (15 mL), extracted with ethyl acetate (2×50 mL), dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by flash column chromatography (silica gel from QingDao, 200-300 mesh, 33% ethyl acetate/hexanes) afforded 2-{4-[1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl]-phenyl}-propan-2-ol (220 mg, 100%): LC/MS m/e calcd for C29H29FN2O3S [M+H]+ 505.63, observed 505.2.
