Reaction Steps

To 5-bromo-3-(2-fluoro-3-methoxy-benzoyl)-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester (86, 350.0 mg, 0.78 mmol) in tetrahydrofuran (30 mL) and water (10 mL) were added 2-thiophene boronic acid (190 mg, 1.49 mmol), tetrakis(triphenyl-phosphine)palladium(0) (40.0 mg, 0.0346 mmol) and potassium carbonate (780 mg, 5.64 mmol) under an atmosphere of nitrogen. The reaction mixture was refluxed for 2 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated to give crude compound (87, 0.30 g, 85%).
