Tetrabutylammonium Fluoride → N-tert-butyl-4-[2-cyclopentyl-1-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-vinyl]-benzamide

Participants

Reaction Steps

A solution of 4-[1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl]-N-tert-butyl-benzamide (1.0 g, 1.83 mmol) in tetrahydrofuran (0.5 mL) and a tetrabutylammonium fluoride solution in tetrahydrofuran (1 M, 10 mL, 10 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 concentrated in vacuo to afford N-tert-butyl-4-[2-cyclopentyl-1-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-vinyl]-benzamide (380 mg, 51.1%) as a white solid: LC/MS m/e calcd for C25H28FN3O [M+H]+ 406.52, observed 406.0.
