Reaction Steps

A mixture of 2-methylimidazole (8.0 g, 97.5 mmol) and 4-fluorophenacyl bromide (21.16 g, 97.5 mmol) dissolved in ethyl acetate (40 ml) at ambient temperature was treated with tiethylamine (16.4 ml, 117 mmol) and the cloudy mixture heated at reflux for 16 hours. The mixture was cooled to ambient temperature and diluted with ethyl acetate and water, washed with water and brine, dried and evaporated to dryness. The residue was recrystallised (3×) from dichloromethane/methanol/isohexane to give 1-(4-fluorophenyl)-2-(2-methylimidazol-1-yl)ethanone (1, 9.0 g, 42%).
