Procedure

To a microwave vial containing 5-(3,5-dimethylisoxazol-4-yl)-1-methyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2(3H)-one (52 mg, 0.14 mmol, 1 equiv.) was added 5-bromo-6-(trifluoromethoxy)quinoline (124 mg, 0.42 mmol, 3 equiv.), Cs2CO3 (230 mg, 0.70 mmol, 5 equiv.) and PEPPSI™-IPr catalyst (9.5 mg, 0.014 mmol, 0.1 equiv.) and dissolved in DME-H2O (4 mL, 0.2 M, 2/1, v/v). The mixture was heated to 120° C. for 30 min in microwave. The reaction was concentrated in vacuo and purification was then carried out by reverse phase HPLC.
