실험 절차

To a solution of 1-tert-butyl-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl trifluoromethanesulfonate (200 mg) obtained in Step C of Example 86 in toluene (20 ml) were added 3-aminobenzenesulfonamide (146 mg), tris(dibenzylideneacetone)dipalladium (51.8 mg), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)(92.6 mg) and cesium carbonate (369 mg), and the mixture was heated overnight with reflux under nitrogen atmosphere. The reaction mixture was extracted with water and ethyl acetate, and the organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (29.6 mg).
