To a vial containing cesium carbonate (1391 mg, 4.27 mmol) was added 4-(benzo[d]thiazol-2-ylamino)phenol (1035 mg, 4.27 mmol), and 4-(2-fluoropyridin-3-yl)cyclohex-3-enol (330 mg, 1.708 mmol) followed by NMP (2.2 mL). The reaction was heated at 200° C. for 2 h with microwave irradiation. The black mixture was diluted with ethyl acetate and washed with 5N NaOH before drying over sodium sulfate, filtering, and concentrating under reduced pressure to a brown residue. Purification by column chromatography (ethyl acetate/dichlormethane) afforded 4-(2-(4-(benzo[d]thiazol-2-ylamino)phenoxy)pyridin-3-yl)cyclohex-3-enol (44.8 mg, 0.108 mmol, 3, steps, 6.31% yield) as a pale brown oil. MS (ESI, pos. ion) m/z: 416.1 (M+1). IC50 (uM) +++++.
