| Abstract: | 2-cholo-3-iodopyridine is an important raw material for producing 2-chloro-3-（trifluoromethyl） pyridine, which is the intermediate for the synthesis of flazasulfuron. 2-cholo-3-iodopyridine was synthesized by the process of the diazotization and the iodination from 2-chloro-3-pyridinamine. The yield of the product was about 80% and the structure was confirmed by 1HMR and IR. |
