실험 절차
To a solution of 6-chloropyridazin-3-amine (2.35 g, 18.1 mmol, 1.0 equiv) in ethanol (15 mL) was added 1-chloropropan-2-one (2.92 mL, 36.3 mmol, 2.0 equiv) and triethylamine (2.53 mL, 18.1 mmol, 1.0 equiv). The solution was heated at 150° C. for 30 min then quenched with water. Purification by column chromatography using 30% ethyl acetate in hexanes elution gave 2.43 g of the brown solid, 80%.
