A mixture of 2,3-diamino-5-bromopyridine (0.94 g, 5 mmol, Aldrich) and disuccinimido carbonate (1.28 g, 5 mmol, Aldrich) in chloroform (50 mL) was heated at reflux for 12 h. The solvent was removed in vacuo and the residue was purified by recrystallization from 40% EtOAc/hexane to give the title compound as a brown solid. MS (ESI, pos. ion) m/z: 214 (M+1).
