Reaction Steps

2-{[(2R,6S)-2,6-Dimethyl-4-morpholinyl]methyl}-N-[1-methyl-6-(4,4,6,6-tetramethyl-1,3,2-dioxaborinan-2-yl)-1H-indazol-4-yl]-1,3-thiazole-4-carboxamide (50 mg), N-(5-bromo-2-chloro-3-pyridinyl)methanesulfonamide (27 mg), tripotassium phosphate (61 mg) and Pd(dppf)Cl2 (7 mg) were added to 1,4-dioxane (0.5 ml) and water (0.5 ml) and heated under microwave irradiation for 10 min at 100° C. The reaction was passed through a 2 g silica SPE cartridge, washing with MeOH then evaporating to dryness. The residue was purified on silica, eluting with 0-100% EtOAc/cyclohexane over 30 min to give the title compound (27 mg).
