실험 절차

To a stirred solution of hydrazine hydrate (30.0 equivalents), water (4 ml/gm of pyridine), and ethanol (2 ml/gm of pyridine) was added 2-chloro-5-nitropyridine (1 equivalent). The reaction mixture was stirred at 20° for 16 hours (a very thick green slurry forms). The precipitate was isolated by filtration and the solid was washed with methanol and then ether to give a green solid. The product was used without further purification; yield 77.3%; m.p. 205°-207°. IR {KBr): 3340, 3200, 2980, 1670, 1605, 1580, 1485, 1420, 1330, 1300, 1120, 980, 830, 770 cm-1.
