Procedure
To a 5 mL microwave vial were added methyl 1-{[1-(3-bromobenzyl)-5-(quinolin-2-ylmethoxy)-1H-benzimidazol-2-yl]methyl}cyclopentanecarboxylate (94 mg, 0.16 mmol), CuCN (31 mg, 0.34 mmol), pyridine (0.5 mL) and DMA (1.5 mL). The vial was flushed with N2, then capped and irradiated in the microwave at 200° C. for 4 h. The resulting mixture was cooled to RT, poured into water (10 mL) and extracted with EtOAc. The organics were concentrated to dryness and the resulting residue was purified by FCC to provide 40 mg of the title compound. MS (ESI): mass calcd. for C33H30N4O3, 530.63; m/z found, 531.2 [M+H]+.
