Reaction Steps
A mixture of 4-fluorobenzonitrile (3.63 g, 30 mmol), 2-phenylimidazole (3.72 g, 30 mmol) and anhydrous K2CO3 (4.15 g, 30 mmol) in dry DMSO (30 ml) was heated at 100° C. for 20 hours under a nitrogen atmosphere. After cooling to room temperature, the reaction mixture was poured into an ice-cold saturated aqueous NH4Cl (100 ml) solution and the whole extracted with Et2O (150 ml×2). The combined extracts was washed with water (100 ml), brine (80 ml), dried over MgSO4 and solvent removed under reduced pressure. The resultant residue was purified by column chromatography (SiO2 ; dichloromethane:ethyl acetate:ethanol=20:1:1) to afford title compound (3.61 g, 49%).
