Cl[C:2]1[C:7]([N+:8]([O-:10])=[O:9])=[CH:6][CH:5]=[CH:4][N:3]=1.[CH2:11]([NH2:13])[CH3:12].O>C1COCC1>[CH2:11]([NH:13][C:2]1[C:7]([N+:8]([O-:10])=[O:9])=[CH:6][CH:5]=[CH:4][N:3]=1)[CH3:12]To a solution of 2-chloro-3-nitropyridine (51 g, 325 mmol) in THF (650 mL) was added a 2 M solution of ethylamine in THF (365 mL, 731 mmol). The reaction was stirred at room temperature overnight. The reaction mixture was poured into water (˜1.5 L) and the resulting solid was filtered and dried under reduced pressure to give the title compound (52 g).
