A mixture of 2-chloro-5-bromopyrimidine (2.5 g, 13 mmol), methylamine hydrochloride (7.9 g, 116 mmol), and diisopropylethylamine (18 mL, 103 mmol) in 43 mL acetonitrile was heated in a sealed vessel for 16 h. The reaction was partitioned between EtOAc and water. The organic layer was washed once with brine, dried over anhydrous sodium sulfate, filtered, and concentrated to give 5-bromo-N-methylpyrimidin-2-amine. MS m/z=188 [M+H]+. Calc'd for C5H6BrN3: 187.
