Procedure

To phenyl-(-1H-pyrrolo[2,3-b]pyridine-5-yl)-amine (70, 17.0 mg, 0.09 mmol) in methanol (5.0 mL) were added potassium hydroxide (92.0 mg, 1.6 mmol) and propane-1-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (73, 19.0 mg, 0.072 mmol, prepared as described in Example 7) under an atmosphere of nitrogen. The reaction was stirred for 12 hours at room temperature. The reaction was concentrated and purified by silica gel column chromatography eluting with 1% methanol in dichloromethane to give the compound (71, 17 mg, 50%). MS (ESI) [M+H+]+=473.5.
