Reaction Steps

A solution of 4-cyclopentoxy-2-[(4-chlorophenoxy)methyl]-1-[3-(piperidin-4-yl)propyl]benzimidazole trifluoroacetate (0.29 mmol, 1 eq) in anhydrous N,N-dimethylformamide (2 ml) was treated with potassium carbonate (120 mg, 0.87 mmol, 3 eq) and 3-phenylpropyl bromide (87 mg, 0.43 mmol, 1.5 eq). The resulting mixture was stirred at 80° C. for six hours. The reaction was quenched by the addition of water (5 ml). The aqueous fraction was extracted with ethyl acetate (3×10 ml). The organic fractions were combined, washed with water (3×10 ml), and brine (1×10 ml), and then dried over sodium sulfate. The solvents were removed in vacuo. The residue was further purified by column chromatography to yield the title product as a white crystalline solid.
