Reaction Steps
To a 20 mL vial were added ethyl 1-{[1-(3-bromobenzyl)-5-(quinolin-2-ylmethoxy)-1H-benzimidazol-2-yl]methyl}cyclopentanecarboxylate (57 mg, 0.09 mmol), THF (1 mL) and MeOH (1 mL) followed by LiOH (1 mL, 1 M). The reaction mixture was capped and heated to 80° C. for 3 h. The mixture was then cooled to RT, water (5 mL) was added to the mixture and the pH was adjusted to 4 using 1 M HCl. To this mixture was added DCM (5 mL) and stirred for 1 h at RT. The organic layer was separated and the aqueouse layer was further extracted with DCM. The combined organics were dried, filtered and concentrated to dryness. The residue was then purified by FCC to provide the title compound.
