実験手順
A mixture of 2-chloro-3-nitropyridine (1 g, 6.31 mmol), ethyl 4-pyridinecarboxylate (1.19 g, 7.57 mmol) and potassium carbonate (1.31 g, 9.47 mmol) in n-butanol (25 mL) was stirred at reflux for 2 hours, cooled to r.t., poured into water and extracted with diethyl ether. The combined organic layers were washed with brine, dried on Na2SO4 and evaporated to dryness in vacuo to afford a residue, which was purified by flash chromatography (EtOAc—Petroleum Ether 2:8) affording the title product (1.38 g).
