To a 5 mL microwave vial were added ethyl 1-((1-(4-bromobenzyl)-5-(quinolin-2-ylmethoxy)-1H-benzo[d]imidazol-2-yl)methyl)cyclopentanecarboxylate (62 mg, 0.1 mmol), Pd(PPh3)4 (12 mg, 0.01 mmol), furan-3-boronic acid (18 mg, 0.16 mmol), K3PO4 (99 mg, 0.47 mmol), DME (1.1 mL) and water (0.56 mL). The vial was capped and irradiated in the microwave reactor at 120° C. for 30 minutes. The mixture was then partitioned between water (20 mL) and EtOAc (20 mL). The layers were separated and the aqueous further extracted with EtOAc (2×20 mL). The organics were combined, dried (Na2SO4), filtered and concentrated to dryness. The residue was purified using reverse phase HPLC to afford the title compound. MS (ESI): mass calcd. for C37H35N3O4, 585.26; m/z found, 586.2 [M+H]+.
