2-Amino-4,6-dimethyl pyrimidine → 2-Amino-5-bromo-4,6-dimethylpyrimidine

Participants

Reaction Steps

To a stirred solution containing 4.31 g (34.75 mmol) of 2-amino-4,6-dimethylpyrimidine (2) in 150 mL of acetonitrile were added 6.15 g (52.12 mmol) of N-bromosuccinimide. The reaction mixture was stirred at room temperature under argon atmosphere for 3 h. The formed precipitate was filtered and dried to afford the expected product as a white solid: yield 5.93 g (83%). 1H-NMR (CDCl3) δ 5.19 (br, 2H), 2.44 (s, 6H); 13C-NMR (CDCl3) δ 166.28, 160.73, 109.60, 24.70.
