Reaction Steps

A reaction tube was charged with Pd(Ph3P)4 (13.6 mg, 11.8 μmol), 2.0 M aqueous sodium carbonate (235 μl, 471 μmol), 6-bromo-N-isopropylbenzo[d]thiazol-2-amine (63.9 mg, 235 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) and 0.9 mL EtOH. The tube was sealed and the mixture was heated at 80° C. for 3 h. The mixture was concentrated and the crude material was purified by silica gel chromatography 0-10% MeOH/CH2Cl2 and reverse phase chromatography to provide N-(2-chloro-5-(2-(isopropylamino)benzo[d]thiazol-6-yl)pyridin-3-yl)-4-methoxybenzenesulfonamide (26 mg, 23%) as an off-white solid. MS (ESI pos. ion) m/z calc'd for C22H21ClN4O3S2: 489.0/491.0. found 488.9/491.0.
