実験手順

2-Methyl-N-[2-(tetrahydro-2H-pyran-2-yl)-6-(4,4,6,6-tetramethyl-1,3,2-dioxaborinan-2-yl)-2H-indazol-4-yl]-1,3-thiazole-4-carboxamide (0.75 g), 5-bromo-2-chloro-3-pyridinamine (0.39 g), sodium carbonate (0.66 g) and Pd(dppf)Cl2 (0.114 g) were weighed to a 10-20 ml microwave vial and 1,4-dioxane (8 ml) then water (8 ml) were added. The reaction was heated at 140° C. for 20 min. The reaction was passed through a 10 g silica cartridge, washing with methanol:DCM (1:1, v/v). The solvent was evaporated and the residue was purified on a 40 g ISCO companion silica cartridge, eluting with 1.5-7.5% methanol in DCM (containing 1% ammonia) at 40 ml/min. Pure fractions were combined and evaporated to dryness to give title compound (335 mg).
