Procedure

To a 10 mL flask were added 3-(1-(4-formylbenzyl)-5-(quinolin-2-ylmethoxy)-1H-benzo[d]imidazol-2-yl)-2,2-dimethylpropanoic acid (160 mg, 0.31 mmol), 3,3-difluoropiperidine (58 mg, 0.37 mmol), sodium triacetoxyborohydride (130 mg, 0.61 mmol) and DCE (3.0 mL) and was stirred at RT overnight. The mixture was diluted with DCM (5 mL) and poured into water (10 mL) then extracted with DCM (3×10 mL), dried over Na2SO4, and concentrated to dryness. The residue was purified using FCC to provide the title compound.
