| Abstract: | 2,6-Dichloropyridine was synthesized from chlorination of pyridine under UV irradiation in the presence of chlorine under the optimal conditions:pyridine:chlorine (molar ratio)=1:2.2 and 190～210℃.Then 2,6-dichloropyridine was hydrolyzed by base and converted into 6-chloro-2(1H)- pyridinol with 85% yield under pressure.The final product was confirmed by elemental analysis,IR, ~1H NMR and MS.The results showed that the synthetic method was quite reliable. |
