Versuchsvorschrift

Into a round bottom flask 1H-pyrrolo[2,3-b]pyridine-4-carbonitrile (5, 0.054 g, 0.38 mmol), N-(2,4-difluoro-3-formyl-phenyl)-4-trifluoromethyl-benzenesulfonamide (4, 0.179 g, 0.49 mmol), 0.75 mL of methanol and potassium hydroxide (0.103 g, 1.89 mmol) were combined. The reaction was stirred at room temperature for 46 hours, then neutralized with 0.1 N aqueous hydrochloric acid and extracted 3× with ethyl acetate. The organic layers were combined and washed with brine, then dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The material was purified by silica gel column chromatography eluting with ethyl acetate and hexane. The appropriate fractions were combined and the solvent removed under vacuum to provide the desired compound (6, 0.018 g). MS (ESI) [M+H+]+=509.1.
