Procedure

To (3,5-Bis-difluoromethoxy-phenyl)-(5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (P-1519, 29.0 mg, 0.067 mmol) in acetonitrile (4.0 mL) were added phenylboronic acid (12.2 mg, 0.10 mmol), Tetrakis(triphenylphosphine)palladium(0) (10.0 mg, 8.65E-6 mol) and 1.0 M potassium carbonate in water (1.5 mL). The reaction was microwaved (300 watts) at 160° C. for 7 minutes. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated, and purified with silica gel column chromatography to give the compound as a white solid (P-1521, 9.4 mg, 33%). MS (ESI) [M+H+]+=431.2.
