Procedure

A mixture of 7-chloro-1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl trifluoromethanesulfonate (100 mg), (4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-thienyl)acetonitrile (84.0 mg) obtained in Step A of Example 93, tetrakis(triphenylphosphine)palladium(0) (13.0 mg) and 2M aqueous sodium carbonate solution (0.200 mL) 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 mixture 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 (70.2 mg).
