A solution of 2,5-dibromopyridine (10 g, 42.3 mmol) in aqueous dimethylamine (50 mL) was refluxed overnight. The volatiles were removed in vacuo, and the residue was treated with EtOAc/PE. The precipitates were collected by filtration and dried to give the title compound. MS (m/z): 201 (M+H)+, 203 (M+H)+.
