Reaction Steps

3-Bromopyridine-4-carboxylic acid (5.0 g) was dissolved in thionyl chloride (50 ml) and the solution heated under reflux for 4 hours, cooled and evaporated in vacuo. Re-evaporation of added toluene gave 3-bromopyridine4-carbonyl chloride, m.p.151°-154° C. (dec.) (5.45 g) as a green solid.
