2-Bromopyridine reacts with butyllithium to give 2-lithiopyridine, [2] which is a versatile reagent. [3] Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using either sodium dithionite or sodium sulfide with sodium hydroxide to introduce the thiol functional group.
