Ethanol → 1H-Pyrrolo(2,3-b)pyridine

Participants

Reaction Steps

A mixture of 1-benzenesulfonyl-2-[2-cyclopentyl-1-(6-methoxy-pyridin-3-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (110 mg, 0.24 mmol), ethanol (6 mL), tetrahydrofuran (3 mL) and an aqueous sodium hydroxide solution (10%, 1 mL) was heated at 40° C. for 4 h. The mixture was diluted with ethyl acetate (100 mL), washed with water, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 2-[2-cyclopentyl-1-(6-methoxy-pyridin-3-yl))-vinyl]-1H-pyrrolo[2,3-b]pyridine (72 mg, 94%) as a white solid: LC/MS m/e calcd for C20H21N3O [M+H]+ 320.41, observed 320.0.
