Trichloroisocyanuric Acid → 5-Acetylfuro(2,3-c)pyridine

Participants

Reaction Steps

1-(Furo[2,3-c]pyridin-5-yl)ethanol (356 mg, 2.19 mmol) was dissolved in acetone (11 mL), and added 2,2,6,6-tetramethylpiperidine 1-oxyl (34 mg, 220 μmol) at room temperature. Then, the reaction solution was added 1,3,5-trichloro-2,4,6-triazinetrione (560 mg, 2.41 mmol), and stirred at the same temperature for 30 minutes. The reaction solution was concentrated in vacuo, added water and a saturated aqueous solution of sodium hydrogen carbonate under ice-cold conditions, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and the title compound (119 mg (yield 34%)) was obtained as a yellow solid.
