실험 절차

A reaction tube was charged with sodium carbonate (353 μl, 706 μmol), Pd(Ph3P)4 (16 mg, 14 μmol), N-(2-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)-4-methoxybenzenesulfonamide (100 mg, 235 μmol), 6-bromoquinolin-2-amine (53 mg, 235 μmol) and 1.2 mL EtOH. The tube was sealed and the mixture was heated at 90° C. for 2 h. The mixture was diluted with CH2Cl2 and washed with water. The organic portion was dried with MgSO4, filtered and concentrated. The crude material was dissolved in MeOH/DMSO and purified by reverse phase chromatography, 10-90% ACN/0.1% TFA in water over 15 min. The aqueous portion was brought to ˜pH 7 and extracted. The organic portion was dried, filtered and concentrated to provide N-(5-(2-aminoquinolin-6-yl)-2-chloropyridin-3-yl)-4-methoxybenzenesulfonamide (12 mg, 12% yield) as a light yellow solid. MS (ESI pos. ion) m/z calc'd for C21H17ClN4O3S: 440.9/442.9; found 441.0/443.0. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.88 (s, 3 H), 6.88 (br s, 2 H), 6.89 (d, 1 H, J=8), 7.15-7.18 (m, 2 H), 7.61 (d, 1 H, J=8), 7.75-7.80 (m, 3 H), 7.97-8.00 (m, 2 H), 8.03-8.06 (m, 1 H), 8.62-8.63 (m, 1 H), 10.46 (br, s, 1 H).
