실험 절차

Ethyl 1,2,4-triazine-3-carboxylate (7 g, 45.8 mmol), cyclopentanone (4.9 mL, 55.0 mmol), and pyrrolidine (4.6 mL, 55.0 mmol) in toluene (100 mL) were heated to reflux for 12 h. The mixture was purified by column on silica gel chromatography (PE/EtOAc=5:1) to give the title compound (2.02 g, 25%) as a brown oil. LCMS: 192 (M+1)+
