Reaction Steps

4,4,5,5-Tetramethyl-2-[4-(trifluoromethyl)cyclohex-1-en-1-yl]-[1,3,2] dioxaborolane (163 mg), [1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloride dichloromethane complex (37 mg), sodium carbonate (144 mg) and water (1.0 ml) were added at room temperature to a solution of N-(6-bromo-5-methylpyridin-3-yl)-5-methyl-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxamide (200 mg) described in Reference Example 189 in 1,4-dioxane (3.0 ml), and stirred at 100° C. under radiation of microwave for an hour. After completion of the reaction, water and ethyl acetate were added, filtered through Celite and the filtrate was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated. The resulting residue was purified with silica gel column chromatography (chloroform/methanol) to give the titled compound (146 mg) as a white solid.
