Reaction Steps

5-Bromo-3-(4-methoxy-benzoyl)-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester (117, 100.0 mg, 0.23 mmol), thiophene-2-boronic acid (59 mg. 0.46 mmol), tetrakis(triphenylphosphine)palladium(0) (20.0 mg, 0.017 mmol), potassium carbonate (80 mg, 0.58 mmol), tetrahydrofuran (15.0 mL) and water (5.0 mL) were combined under an atmosphere of nitrogen. The reaction mixture was refluxed overnight, then 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 chromatography to give compound 118 (100 mg).
