Conditions

Temperature: 200 °C

Procedure

A mixture of (1H-benzo[d]imidazol-2-yl)(4-hydroxyphenyl)methanone (0.485 g, 2.035 mmol), 3-(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-2-fluoropyridine (0.311 g, 1.356 mmol), and cesium carbonate (1.326 g, 4.07 mmol) in NMP (5 mL) in a sealed tube was heated at 200° C. in 2 h. The reaction mixture was cooled, taken in H2O, filtered the dark brown solid, purified by ISCO (50% EtOAc/Hexanes) to give the expected product as a tan solid. MS (ESI, pos. ion) m/z: 448.1 (M+1). IC50 (uM) +++++.
