To 5-bromo-7-azaindole (67, 170.0 mg, 0.86 mmol) in methanol (7.0 mL) were added propane-1-sulfonic acid (4-fluoro-3-formyl-phenyl)-amide (672, 220.0 mg, 0.90 mmol) and potassium hydroxide (0.50 g, 0.0089 mol) under an atmosphere of nitrogen. The reaction was stirred at room temperature overnight. The reaction was poured into water, acidified with 1N HCl to pH=5, 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 10% methanol in methylene chloride to give the compound (673, 55.0 mg, 14.0%). MS (ESI) [M+H+]+=442.1, 444.1.
