Reaction Steps

A mixture of 1-(2-chloro-5-((5-fluoro-2-methylphenyl)ethynyl)pyridin-4-yl)ethanone (700 mg, 2.0 mmol), sodium acetate (320 mg, 3.9 mmol), and hyroxylamine hydrochloride (254 mg, 3.65 mmol) in ethanol (11 mL) and dichloroethane (1.6 mL) was heated at 70° C. for 15 minutes. The cooled reaction mixture was evaporated in vacuo to afford a residue that was redissolved in ethyl acetate (150 mL) and washed with water (100 mL). The organic layer was separated, dried over sodium sulfate, filtered, and evaporated in vacuo to afford a white solid that was used in the next step without further purification.
