Reaction Steps

A mixture of 1-(6-fluoro-1-tosyl-1H-pyrrolo[3,2-b]pyridin-5-yl)ethanone (0.7 g, 2.118 mmol), NaOAc (1.73 g, 21.1 mmol), and hydroxylamine hydrochloride (0.735 g, 10.55 mmol) in EtOH (20 mL) was heated at 60° C. for 1 h. The reaction mixture was concentrated under reduced pressure, water (200 mL) was added, and the mixture was extracted with EtOAc (50 mL×3). The combined extracts were concentrated under reduced pressure to afford 0.66 mg (90%) of 1-(6-fluoro-1-tosyl-1H-pyrrolo[3,2-b]pyridin-5-yl)ethanone oxime as a white solid. MS (ESI): m/z=348.2 [M+1]+.
