Reaction Steps

To a solution of 2-amino-5-bromo-3-methylpyridine (300 mg) in N,N-dimethylaniline (486 mg) was added acetyl chloride (138 mg), and the mixture was stirred for 3 hours at 70° C. The reaction mixture was poured into water, and extracted with ethyl acetate. The extract was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by silica gel column chromatography (chloroform) to give 2-acetamido-5-bromo-3-methylpyridine (120 mg).
