실험 절차

A mixture of methyl 4,6-dichloropyridazine-3-carboxylate (0.69 g, 3.33 mmol) and 6-tert-butylpyridin-2-amine (1.00 g, 6.67 mmol) was dissolved in acetonitrile (3 mL) and heated at 130° C. for 14 h The dark brown mixture was cooled, concentrated onto silica, and purified by chromatography (silica, 80 g, 0-20% acetone in dichloromethane, 40 min) to give methyl 4-(6-tert-butylpyridin-2-ylamino)-6-chloropyridazine-3-carboxylate (372 mg, 1.16 mmol, 35%) as a yellow solid. MS (EI/CI) m/z: 321.0 [M+H].
