Versuchsvorschrift

A solution of ammonium hydroxide (6.6 g, 0.124 mol) and sodium hydroxide (4.8 g, 0.120 mol) in water (45 mL) was added to 2,6-dichloro-3-nitropyridine (12.0 g, 0.62 mol) in ethanol (240 mL). The reaction was refluxed for 2 h, cooled to room temperature and filtered. The pale yellow solid was dried overnight to give the title compound. 1H NMR (500 MHz, CDCl3) δ 8.87 (d, J=9 Hz, 1H), 7.8 (br s, 1H), 6.73 (d, J=9 Hz, 1H), 5.9 (br s, 1H).
