Hydrogen bromide gas is introduced into a solution of 30 g (0.130 mole) of 2,6-diphenylpyridine in 150 ml of toluene. The solid which forms is isolated by vacuum filtration. The filtrate is retreated with hydrogen bromide until no more solid is formed. The solid is then dried in vacuo. The product has a melting point of 161° C.-162° C.
