Reaction Steps

Diethyl (3-nitropyridin-2-yl)-malonate (12.5 g, 0.044 mol) was dissolved in DMSO (150 mL) and water (0.79 mL, 0.044 mol) and lithium chloride (4.65 g, 0.11 mol) were added at room temperature under nitrogen. The reaction was warmed to 100° C. 12 hours and more lithium chloride (1 g) was added to the reaction. The reaction was heated for another 5 hours and cooled to room temperature. Brine (150 mL) was added to the reaction before extracting with EtOAc (3×, 275 mL each). The organics were combined and dried over sodium sulfate, then concentrated in vacuo. The resulting residue was triturated with diethyl ether and collected by filtration (8.6 g, 92% yield). 1H NMR 400 MHz (DMSO-d6) δ8.83 (m, 1H); 8.53 (m, 1H); 7.65 (m, 1H); 4.23 (s, 2H); 4.07 (m, 2H); 1.16 (m, 3H).
