In a round bottom flask, 5-(1H-pyrrolo[2,3-b]pyridin-5-yl)-pyridine-2-carboxylic acid ethylamide (38, 71 mg, 0.27 mmol), propane-1-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (58, 84.2 mg, 0.32 mmol) and potassium hydroxide (44.9 mg, 0.80 mmol) were combined with 1.1 mL of methanol. The reaction was stirred for 2 hours at room temperature. The reaction solution was neutralized with 0.1 N hydrochloric acid, then extracted 3× with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting residue was purified by silica gel column chromatography to provide the desired compound (73, 55 mg). MS (ESI) [M+H+]+=530.1.
