To a solution of 6-chloro-4-(5-{[(2R,6R)-2,6-dimethyl-4-morpholinyl]methyl}-1,3-oxazol-2-yl)-1-(phenylsulfonyl)-1H-indazole (109.5 mg, 0.225 mmol), N-[2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methanesulfonamide (148 mg, 0.450 mmol) and sodium bicarbonate (56.7 mg, 0.675 mmol) in 1,4-Dioxane (5 mL) and Water (1.5 mL) stirred in air at room temp was added solid Solvias Catalyst (12.60 mg, 0.022 mmol). The reaction mixture was stirred at 120° C. for 2 hr. After this time, sodium hydroxide solution (2N, 0.5 mL) was added and the reaction mixture left to stir at room temperature for two hours. On cooling, the reaction mixture was passed through a celite cartridge (10 g) and washed with ethyl acetate. The resulting solution was evaporated and the crude residue purified by MDAP (Method C). Appropriate fractions were combined and concentrated in vacuo to afford the title compound (43 mg).
