Reaction Steps

Methyl pyrazine-2,3-dicarboxylate (2 g, 10.2 mmol) was dissolved in EtOH (5 mL). Diethanolamine (2.14 g, 20.4 mmol) was added and the mixture was heated under reflux for 5 h. After cooling the solvent was evaporated and the residue was purified by silica gel chromatography (CHCl3 /MeOH, 8:2) to afford the title compound (2.5 g, 71.4%).
