A mixture of N-(4-(3-chloropyrazin-2-yloxy)-2-fluorophenyl)benzo[d]thiazol-2-amine (2098 mg, 5.63 mmol), 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)cyclohex-2-enone (1000 mg, 4.50 mmol), dichlorobis(triphenylphosphine)palladium(ii) (316 mg, 0.450 mmol), and sodium carbonate (1432 mg, 13.51 mmol) in DME/H2O/EtOH (7:3:2, 36 ml) was heated to 140° C. for 3 h. Water (100 ml) was added and the reaction mixture was extracted with EtAOc (3×100 ml). The combined organic layers were washed with brine and dried over sodium sulfate. Filtration and concentration under reduced pressure afforded 3-(3-(4-(benzo[d]thiazol-2-ylamino)-3-fluorophenoxy)pyrazin-2-yl)cyclohex-2-enone. MS (ESI, pos. ion) m/z: 433.0 (M+1). IC50 (uM) +++++.
