Reaction Steps

A solution of 4-[3-bromopropoxy]-2-[(4-chlorophenoxy)methyl]-1-[3-[1-(t-butoxycarbonyl)piperidin-4-yl]propyl]benzimidazole (77 mg, 0.124 mmol, 1 eq) in anhydrous N,N-dimethylformamide (2 ml) was treated with potassium carbonate (51.3 mg, 0.37 mmol, 2 eq) and 4-(methyl)piperidine (0.19 mmol, 1.5 eq). The resulting mixture was stirred at 80° C. for six hours. The reaction was quenched by the addition of water (10 ml). The aqueous fraction was extracted with ethyl acetate (3×10 ml). The organic fractions were combined, washed with water (3×10 ml), brine (1×10 ml), and then dried over sodium sulfate. The solvents were removed in vacuo to yield an oily crude product which was purified by flash chromatography to provide the title product.
