Reaction Conditions

Reaction Steps

To a solution of 1-(4-methylpyridin-3-yl)propan-1-one (4.72 g) in acetic acid (35 ml) was added hydrobromic acid (5.5 ml) and the mixture was cooled to 10° C. A solution of bromine (5.0 g) in acetic acid (15 ml) was gradually added to the reaction mixture and the mixture was stirred at 80° C. for one hr. The solvent was evaporated under reduced pressure and the residue was recrystallized from ethyl acetate to give the title compound (5.56 g) as a pale-yellow powder.
