A pyridine compound is reacted with fluorine together with a Brønsted acid-compound or a Lewis acid to form a N-fluoropyridinium salt which is very active to other compounds but is very selective for the preparation of a desired product and this product is very useful for a fluorine-introducing agent which makes it useful for the preparation of fluoro-compound such as thyroid inhibitor.
