6-Amino-3-(4-pyridyl)-2-(4-fluorophenyl)-7-aza-indole (17) (250 mg, 0.822 mmol), N-fluorobenzenesulphonamide (259 mg, 0.822 mmol), and DMF (4 mL) were warmed to 90° C. behind an explosion shield. After 48 h, the reaction was concentrated in vacuo and the residue was purified by flash chromatography (ethyl acetate: hexane 1:1) to afford 6-Amino-5-fluoro-3-(4-pyridyl)-2-(4-fluorophenyl)-7-aza-indole (28): Mass Spectrum (CI) 323 (MH+).
