실험 절차

1-Chloro-4-fluorobenzene (16.3 g, 124 mmol) and imidazole (5.0 g, 73.4 mmol) are dissolved in N,N-dimethylformamide (30 ml) and admixed while stirring with sodium hydride (60% strength in mineral oil; 3.82 g, 95.4 mmol) and then heated at 130° C. for 5 hours. After cooling, the reaction mixture is slowly poured into water. The precipitate formed is subsequently filtered off, washed with petroleum ether and subsequently dried under reduced pressure. This gives 10.3 g of 1-(4-chlorophenyl)imidazole.
