Procedure

To a mixture of 1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl trifluoromethanesulfonate (150 mg) obtained in Step C of Example 35, 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)morpholin-3-one (145 mg) and sodium carbonate (78 mg) in DME/water (1.5 mL/0.070 mL) was added dichloro(1,1′-bis(diphenylphosphino)ferrocene)palladium(II) (21 mg) under nitrogen atmosphere. The reaction mixture was stirred under microwave irradiation at 120° C. for 1 hr. The insoluble substance was removed by the filtration, the filtrate was added to water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by thin layer silica gel chromatography (ethyl acetate/petroleum ether) to give the title compound (143 mg).
