Procedure

A mixture of 1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl trifluoromethanesulfonate (250 mg) obtained in Step C of Example 35, 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)morpholine (265 mg), tetrakis(triphenylphosphine)palladium(0) (35.3 mg) and 2M aqueous potassium carbonate solution (169 mg) in DMF (2 mL) was stirred under microwave irradiation at 130° C. for 1.5 hr. The reaction mixture was added to water, and the filtrate was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (240 mg).
