Procedure

3-(4-Methoxy-benzoyl)-5-thiophen-2-yl-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester (118, 100.0 mg, 0.23 mmol) and methylene chloride (15.0 mL) were combined under an atmosphere of nitrogen. Boron tribromide (1.0 M in methylene chloride, 3.0 mL) was added. The reaction was stirred at room temperature overnight. Methanol (2.0 mL) was added into the reaction mixture. The reaction was concentrated to remove solvents. The residue was extracted with water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified with silica gel chromatography. The product was washed with methanol to provide compound (P-0024, 25.0 mg, 34%). MS (ESI) [M+H+]+=321.
