Mix 1-[[(2-ethoxy)ethyl]-1H-benzimidazol-2-yl][1-(t-butyloxycarbonyl)-4-piperidinyl]methanone (10.07 g, 26.67 mmol) and trifluoroacetic acid (75 mL). Stir at room temperature until the reaction is complete. Pour onto water and carefully neutralize with solid sodium hydrogen carbonate. Extract into ethyl acetate (2×), wash with brine and dry (MgSO4). Evaporate the solvent in vacuo and purify by chromatography to give the title compound.
