A microwave vial was charged with N-[6-bromo-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-yl]-2-methyl-1,3-thiazole-4-carboxamide (50 mg), Solvias catalyst (7 mg), tripotassium phosphate (76 mg), 4-pyridinylboronic acid (15 mg), 1,4-dioxane (0.5 ml) and water (0.1 ml). The mixture was heated under microwave irradiation for a total of 60 min at 80° C. 4-Pyridinylboronic acid (15 mg) was added and the mixture was heated for 30 min at 80° C., then 30 min at 120° C. The reaction mixture was passed through a silica cartridge preconditioned with methanol, washing with methanol, then dried in vacuo. The residue was extracted with DCM/water, dried through a hydrophobic frit and dried in vacuo. The residue was dissolved in DMSO:methanol (1 ml, 1:1, v/v) and purified by MDAP (method E). Appropriate fractions were dried under a stream of nitrogen. The residue was dissolved in methanol and a few drops of 2M HCl (aq) were added and the reaction was stirred for 30 min. The reaction mixture was passed through an aminopropyl cartridge, preconditioned with methanol, washing with methanol, then dried to give title compound, (19 mg).
