Reaction Steps

To a solution of 5-bromo-2-chloro-3-nitropyridine (Matrix, Columbia, USA, 9.8 g, 41.3 mmol) in 250 ml THF was added 8 M methylamine in EtOH (Aldrich, Buchs, Switzerland, 12.9 ml, 103 mmol). The reaction mixture was stirred 1 h at rt then was quenched with 300 ml water. The precipite was filtered and the filtrate concentrated before being filtered again. The yellow solids were combined and dried to give the title compound as a yellow solid (HPLC: tR 3.13 min (Method A)).
