General procedure for synthesis of 2,4,6-trichloropyridine(Y-3)
A mixture of 2,6-dichloropyridine-1-oxide (Y-2) (8.20 g, 0.050 mol) in POCl3 (25 mL) was refluxed for 4 h.
Then, the solvent was evaporated under reduced pressure.
The residue was poured into crushed ice and extracted with petroleum ether (3 * 50 mL).The combined organic phase was dried over K2CO3, filtered, and concentrated in vacuum.
The residue was further purified by flash column chromatography using ethyl acetate/petroleum ether as an eluent to give 2,4,6-trichloropyridine (Y-3) as colorless needles, yield 85%, mp: 32-33 °C.
