실험 절차

2-Fluoro-3-(oxepan-4-yl)pyridine (0.055 g, 0.28 mmol), 4-(benzo[d]thiazol-2-ylamino)phenol (0.20 g, 0.85 mmol), and cesium carbonate (0.28 mL, 0.85 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 yield an orange solid. The solid was slurried in MeOH and filtered to give N-(4-(3-(oxepan-4-yl)pyridin-2-yloxy)phenyl)benzo[d]thiazol-2-amine. MS (ESI, pos. ion) m/z: 418.1 (M+1). IC50 (uM) +++++.
