Reaction Steps
A mixture of 2-chloro-5-iodopyridine (20.0 g), sodium pentafluoropropionate (77.8 g), copper (I) iodide (31.8 g), xylene (84 ml) and N-methylpyrrolidone (84 ml) was heated to 160° C., and stirred while heating under reflux 6 hours. The reaction mixture was cooled to room temperature, and water was poured thereto. Then, the mixture was extracted with methyl-tert-butyl ether. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure to give 2-chloro-5-pentafluoroethyl pyridine.
