Versuchsvorschrift

2-Fluoro-3-(oxepan-4-yl)pyridine (0.061 g, 0.31 mmol), 4-(pyridin-2-ylamino)phenol (0.18 g, 0.94 mmol), and cesium carbonate (0.31 g, 0.94 mmol) were mixed in NMP (0.75 mL). The reaction mixture was placed under a nitrogen atmosphere and stirred at 120° C. for 17 h. The reaction mixture was cooled to room temperature, diluted with water, and extracted with EtOAc (2×). The combined organic layers were washed with 1 M aqueous sodium hydroxide, washed with sat. sodium chloride, dried over magnesium sulfate, and concentrated in vacuo. The resulting crude product was purified by silica gel chromatography to give N-(4-(3-(oxepan-4-yl)pyridin-2-yloxy)phenyl)pyridin-2-amine MS (ESI, pos. ion) m/z: 362.2 (M+1). IC50 (uM) 0.026.
