Reaction Steps

A solution of 2-[3-[(5-bromopentyl)oxy]propyl]-1-(phenylmethyl)benzimidazole (1.7 g) in absolute ethanol (20 ml) containing 1:9 conc. hydrochloric acid:ethanol (3.27 ml) was hydrogenated over pre-reduced 10% palladium oxide on charcoal catalyst (300 mg) in ethanol (5 ml) until the uptake of hydrogen (101 ml) ceased. The mixture was filtered through hyflo and evaporated in vacuo to give an oil, which was dissolved in ether (150 ml) and washed with 8% sodium bicarbonate solution (100 ml), dried and evaporated in vacuo to give an oil. Purification by FCC eluting with hexane-ether (2:3→0:5) gave the title compound as a yellow oil (0.92 g).
