Reaction Steps

Titanium tetrachloride (0,03 mol) is added dropwise to a stirred suspension of zinc powder (0,06 mol) in tetrahydrofuran (30 ml) at -10° C. under dry nitrogen. The mixture is heated to reflux and refluxing is continued for 1 hour. The solution is cooled to 0° C. and 1-benzyl-5-[1-(4-fluorophenyl)-1-oxomethyl]-1H-imidazole (0,005 mol) in tetrahydrofuran (10 ml) and phenylacetaldehyde (0,006 mol) in tetrahydrofuran (10 ml) are added into the mixture, respectively. The mixture is refluxed with stirring for 1 hour. The dark mixture is poured into water (60 ml), tetrahydrofuran is evaporated and the mixture is extracted with methylene chloride (2×100 ml). The methylene chloride solution is washed with 2N sodium hydroxide and water, dried with sodium sulphate and evaporated to dryness. The residue is purified by flash chromatography.
