A reaction tube was charged with N-(2-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)-4-methoxybenzenesulfonamide (157 mg, 0.369 mmol), 6-bromo-N-(cyclohexylmethyl)benzo[d]thiazol-2-amine (80 mg, 0.246 mmol), Pd(PPh3)4 (14.2 mg, 0.012 mmol), 2.0 M aqueous sodium bicarbonate (0.246 mL, 0.492 mmol) and 0.98 mL ethanol. The tube was sealed and the mixture was heated at 85° C. for 2.5 h. The reaction was concentrated, dissolved in 90/10 CH2Cl2/MeOH and passed through a silica plug. The filtrates were concentrated and the crude material was purified by reverse phase chromatography to provide N-(2-chloro-5-(2-(cyclohexylmethylamino)benzo[d]thiazol-6-yl)pyridin-3-yl)-4-methoxybenzenesulfonamide as a slightly yellow solid (7 mg, 5.2%). MS (ESI pos. ion) m/z calc'd for C21H27ClN4O3S2: 543.1/545.1. found 543.0/545.0.
