実験手順

A mixture of N-(5-bromopyrazin-2-yl)-5-methyl-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxamide (300 mg), 4-[4-(4,4,5,5-tetramethyl[1,3,2] dioxaborolan-2-yl)cyclohex-3-en-1-yl]morpholin (185 mg), tetrakis(trophenylphosphine)palladium (0) (81 mg) and sodium carbonate (186 mg) in 1,4-dioxane (7.0 ml) was stirred at 90° C. for four hours. Then, N,N-dimethylformamide (7.0 ml) and bis(diphenylphosphine)ferrocenepalladium (II) dichloride dichloromethane adduct (57 mg) were added at room temperature and stirred at 90° C. for five hours. After completion of the reaction, the reaction solution was cooled to room temperature, water was added, and the precipitated solid was collected by filtration. The resulting residue was purified with silica gel column chromatography (chloroform/methanol) twice to give the titled compound (143 mg) as a white solid.
