Reaction Steps

To a solution of 3.47 g of 2-[1-((4-(1,1-dimethylethyl)phenyl) methyl)piperidine-4-yl]-1H-benzimidazole in 80 ml of acetonitrile, 1.38 g of potassium carbonate and 1.08 ml of 2-chloroethyl-ethyl ether are added and the mixture is refluxed for 8 hours; then is left to cool and poured onto 200 ml of water; it is extracted with ether (3×30 ml) and the ethereal layer is washed with water (3×20 ml) and dried over anhydrous sodium sulfate. The oil obtained by elimination of the ether is purified by column chromatography by using chloroform/methanol (98/2) as eluent, thus obtaining 2 g of 2-[1-((4-(1.1-dimethylethyl)phenyl(methyl) piperidine-4-yl]-1-(2-ethoxyethyl)-1H-benzimidazole. Mp: 51°-53° C.
