Procedure

A solution of 85 g. of 3-phenoxypyridine in 100 ml. of absolute ethanol is treated with 84 g. of 48% hydrobromic acid with stirring and the solution is evaporated to dryness at reduced pressure. The residue is dissolved in warm 2-propanol, the solution is diluted to cloudiness with ether and chilled to crystallize 3-phenoxypyridine hydrobromide; m.p. 132°-134° C. after drying at reduced pressure.
