Reaction Steps
20 g of 5-(3,4-dibromobutyl)picolinic acid was added to 15 ml of thionyl chloride and resulting solution was kept to warm at 50°C for one-half hour. Reaction mixture was evaporated in reduced pressure and resulting oily residue was dissolved in chloroform 100 ml. Through the solution dry ammonia gas was passed for five minutes with cooling. White precipitate was removed by filtration and washed with chloroform. Filtrate and washings are combined and evaporated in reduced pressure. Resulting solid was crystallized from benzene to give 10.2 g of the pure product as platelets.
