Procedure

To aluminum trichloride (4.8 g, 36.0 mmol) in methylene chloride (70.0 mL), under an atmosphere of nitrogen, was added 5-bromo-1H-pyrrolo[2,3-b]pyridine (67, 797 mg, 4.04 mmol) dissolved in methylene chloride (5.0 mL). The reaction was stirred at room temperature for 30 minutes, followed by addition of 3-(propane-1-sulfonylamino)-benzoyl chloride (77, 1.10 g, 4.20 mmol) dissolved in methylene dichloride (4.0 mL). The reaction was stirred at room temperature for 2 hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 30% ethyl acetate in hexane to give a white solid (P-1116, 300.0 mg). MS (ESI) [M−H+]−=420.1, 422.1.
