Participants

Reaction Steps

Imidazole (0.55 g, 8 mmol) is dissolved in dry tetrahydrofaran. The solution is cooled on icebath and SOCl2 (0.16 ml, 2 mmol) is added dropwise to the cooled solution. The mixture is stirred for 10 min. 1-(4-cyanophenyI)-3-(4-fluorophenyl)-1-propanone (0.34 g, 1.3 mmol) is added and the mixture is stirred in room temperature for 4 days. Methylene chloride is added and the mixture is washed with water. The organic layer is dried and the solvent is evaporated. The residue contains 35% of the product (1H NMR) as a 9:1 mixture of the isomers. The product is purified by flash chromatography (eluent CH2Cl2 -MeOH 99:1).
