Substituted pyridine compounds particularly alkyl-substituted pyridines, are directly fluorinated to the corresponding 2-fluoro alkyl-substituted pyridines. Fluorine gas, preferably diluted with an inert gas, is passed into the substituted pyridine, preferably in a solvent, at a temperature of +25 DEG C. to -40 DEG C., preferably about -25 DEG C. |
