Tetrabutylammonium Fluoride → 2-{2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-yloxy}-N,N-dimethyl-acetamide

Participants

Reaction Steps

A solution of 2-{1-benzenesulfonyl-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-yloxy}-N,N-dimethyl-acetamide (340 mg, 0.59 mmol) in tetrahydrofuran (0.5 mL) and a tetrabutylammonium fluoride solution in tetrahydrofuran (1 M, 4 mL, 4 mmol) was stirred at room temperature for 12 h. The mixture was diluted with ethyl acetate (150 mL), and washed with a saturated aqueous ammonium chloride solution, 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}-N,N-dimethyl-acetamide (276 mg, quant.) as a white solid: LC/MS m/e calcd for C25H29N3O4S [M+H]+ 468.59, observed 468.2.
