実験手順

The above 3-chloro-4-methoxy-2-methylpyridin-1-oxide (890 mg) was dissolved in acetic anhydride (12 mL), and the resulting solution was then heated under reflux for 30 minutes. After leaving to cool to room temperature, the reaction solution was concentrated under reduced pressure, and the residue was then purified by silica gel chromatography (hexane-ethyl acetate), so as to obtain the title compound (576 mg) as an oily substance.
