A solution of 5-bromo-6-(trifluoromethoxy)quinoline (obtained by bromination of 6-trifluoromethoxyquinoline) (50 mg, 0.17 mmol), 6-(3,5-dimethylisoxazol-4-yl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2(3H)-one (91 mg, 0.26 mmol), dichloro 1,1-bis(diphenylphosphino)ferrocene palladium(II) dichloromethane (12.7 mg, 0.02 mmol), 1,8-diazabicyclo[5.4.0]undec-7-ene (0.2 mL, 1.37 mmol), DMSO (0.2 mL) and water (0.2 mL) under nitrogen was heated at 120° C. for 1 h. The reaction mixture was filtered and purified by reverse-phase HPLC to give 6-(3,5-dimethylisoxazol-4-yl)-4-(6-(trifluoromethoxy)quinolin-5-yl)-1H-benzo[d]imidazol-2(3H)-one.
