Versuchsvorschrift

To a solution of 1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl trifluoromethanesulfonate (100 mg) obtained in Step C of Example 35 in DMF (4 mL)/water (0.40 mL) were added methyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-2-carboxylate (98.3 mg), tetrakis(triphenylphosphine)palladium(0) (28.2 mg) and potassium carbonate (67.5 mg). The reaction mixture was stirred under microwave irradiation at 130° C. for 30 min. The reaction mixture was diluted with water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (44.9 mg).
