To a vial containing 4-(benzo[d]thiazol-2-ylamino)phenol (819 mg, 3.38 mmol) was added cesium carbonate (918 mg, 2.82 mmol) followed by 4-(2-fluoropyridin-3-yl)cyclohexanol (220 mg, 1.127 mmol) as a solution in NMP (7.5 mL). The reaction mixture was heated to 200° C. for 2.5 h with microwave irradiation. The reaction mixture was diluted with water and extracted with 15% IPA:chloroform before drying over magnesium sulfate, filtering, and concentrating to a dark brown residue under reduced pressure.
