Reaction Steps
4-Chloro-3-nitropyridine (2.00 g, 12.6 mmol) and imidazole (2.25 g, 33.0 mmol) were dissolved in 10 ml of 1,4-dioxane, and 2 ml of triethylamine was added thereto. followed by reaction at 90° to 100° C. for 1.5 hours. Then, the solvent was removed by distillation under reduced pressure, and the residue was purified by silica gel column chromatography [eluent: dichloromethane:methanol=10:1 (v/v)] to obtain 2.31 g of a yellow liquid (yield: 96.4%).
