Abstract
Abstract Reaction of bromine (1 mole) with benzylidene 2-pyridylhydrazone is acetic acid gives benzylidene 2-(N-bromopyridylium)-hydrazone bromide, which has the properties of a typical N-bromo-compound. Bromination in the presence of sodium acetate, or treatment of the N-bromo-compound with bases, leads to 3-phenyl-s-triazolo[4,3-a] pyridine.
