実験手順

4-(2-Fluoropyridin-3-yl)cyclohexanone (0.05 g, 0.26 mmol), 4-(benzo[d]thiazol-2-ylamino)phenol (0.19 g, 0.78 mmol) and cesium carbonate (0.25 g, 0.78 mmol) were mixed in NMP (1 mL). The reaction mixture was placed under a nitrogen atmosphere and stirred at 120° C. for 16 h. The reaction mixture was cooled to room temperature, diluted with water, and extracted with EtOAc (4×). 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 4-(2-(4-(benzo[d]thiazol-2-ylamino)phenoxy)pyridin-3-yl)cyclohexanone. MS (ESI, pos. ion) m/z: 416.1 (M+1). IC50 (uM) +++++.
