Procedure

5-Bromo-3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (200 mg, 0.438 mmol), commercial 1H-pyrazole-3-boronic acid (73.6 mg, 0.637 mmol) and 1,1′-bis(diphenylphosphino)ferrocenepalladium(II)-dichloride dichloromethane adduct (17.8 mg, 0.022 mmol) were combined in dimethylformamide (1.4 mL) and 2 M saturated sodium carbonate (657 μL) under nitrogen. The mixture was heated to 165° C. in the microwave for 900 s. The mixture was diluted with ethyl acetate and the aqueous layer was removed. After drying over sodium sulfate, the crude material was purified by silica gel chromatography to afford 3-(2-methoxy-phenyl)-5-(1H-pyrazol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (156 mg, 80.2%). %). MS: m/z 445 (M+H+).
