To a 5 mL microwave vial were added methyl 1-{[1-(3-bromobenzyl)-5-(quinolin-2-ylmethoxy)-1H-benzimidazol-2-yl]methyl}cyclopentane carboxylate (59 mg, 0.1 mmol), Pd(Ph3)4 (10 mg, 0.008 mmol), (1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazol-5-yl)boronic acid (65 mg, 0.26 mmol), Na2CO3 (0.15 mL, 2 M) and 1,4-dioxane (1.5 mL). The vial was flushed with N2 then capped and placed in a heating block at 100° C. After 16 h the mixture was cooled to RT, transferred to a round-bottomed flask and concentrated to dryness. The residue was purified using FCC to provide the title compound. MS (ESI): mass calcd. for C41H47N5O4Si, 701.94; m/z found 702.0 [M+H]+.
