Reaction Steps

2,0 g of benzylbromide in 5 ml of toluene is added dropwise to the mixture of 4-(1,3-diphenylpropyl)-1H-imidazole (2,6 g), 48% NaOH (10 ml), toluene (20 ml) and tetrabutylammoniumbromide (0,2 g) at room temperature. After addition the reaction mixture is stirred at room temperature for 3 hours. Water is added and the toluene layer is separated. The toluene phase is then washed with water and evaporated to dryness. The residue contains the isomers 1-benzyl-4-(1,3-diphenylpropyl)-1H-imidazole and 1-benzyl-5-(1,3-diphenylpropyl)-1H-imidazole and the former is separated and purified by flash chromatography (methylene chloride-methanol 9,5:0,5).
