N-bromobutanimide → N-[6-(Bromomethyl)pyridin-2-yl]-2,2-dimethylpropanamide

Participants

Reaction Steps

2,2 ethyl-N-(6-methyl-2-pyridinyl)propaneamide (21-1) (32 g) and N-bromosuccinimide (29.6 g) were added to carbon tetrachloride (300 ml) and to the mixture was added AIBN (15 mg), followed by reluxing for 20 hours under light emitted by 500 W lamp. The resulting mixture was cooled to room temperature, filtered, and concentrated under reduced pressure. The residue was purified by column-chromatography (hexane/ethyl acetate=10/1) to yield the compound 21-2 (1.94 g, 5%) as a pure white solid.
