Reaction Steps

To the solution of 1-(6-fluoro-1-methyl-1H-indazol-4-yl)ethanone (900 mg, 4.68 mmol) in EtOH (20 mL) was added hydroxylamine hydrochloride (1.64 g, 23.4 mmol, 5.0 eq.) and NaOAc (3.84 g, 46.8 mmol, 10 eq.). The mixture was stirred at 40° C. overnight, and the solvent was concentrated in vacuo to afford 1-(6-fluoro-1-methyl-1H-indazol-4-yl)ethanone oxime as a white solid (848 mg, 87%). MS (ESI): m/z=208.2 [M+1]+.
