Reaction Conditions

Reaction Steps

2-Fluoro-3-(oxepan-4-yl)pyridine (0.10 g, 0.51 mmol), (1H-benzo[d]imidazol-2-yl)(4-hydroxyphenyl)methanone (0.37 g, 1.54 mmol), and cesium carbonate (0.50 g, 1.54 mmol) were mixed in NMP (1.5 mL). The reaction mixture was placed under a nitrogen atmosphere and stirred at 140° C. for 96 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 (EtOAc/hexanes) to give (1H-benzo[d]imidazol-2-yl)(4-(3-(oxepan-4-yl)pyridin-2-yloxy)phenyl)methanone. MS (ESI, pos. ion) m/z: 414.1 (M+1). IC50 (uM) +++++.
