Reaction Steps
4-bromopyridine-2,6-diamine (3 g, 15.96 mmol) was dissolved in EtOH (300 mL). Ethyl bromopyruvate (2.34 mL, 16.8 mmol, 90% tech grade) was added. The mixture was heated at reflux for 5 h. The solvent was evaporated under reduced pressure to give a dark tan foam which was triturated with 200 mL of saturated NaHCO3 overnight. The solids were filtered, washed with 2×10 mL of saturated NaHCO3, then triturated with EtOAc (100 mL) twice, filtered and air dried to give the desired product as a tan powder weighing 3.15 g (70%).
