실험 절차

A suspension of 2-methyl-4-pyrrolidin-1-yl-quinoline-7-carboxylic acid amide (50 mg, 0.20 mmol), 4-iodobenzonitrile (45 mg, 0.20 mmol), xantphos (6.8 mg, 12 μmol), cesium carbonate (89 mg, 0.27 mmol), and palladium(II) acetate (1.8 mg, 8 μmol) in 1,4-dioxane (0.5 mL) was stirred under argon at 50° C. for 22 h, then the reaction mixture was partitioned between sat. aq. sodium hydrogencarbonate solution and dichloromethane. The organic layer was separated, washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 19:1) afforded the title compound (18 mg, 26%). Light yellow solid, ISP-MS: m/e=357.3 ([M+H]+).
