Reaction Steps

4-(4-Fluorophenyl)-5-(3-pyridyl)-1H-2-imidazolethiol (8.2 g) was added portionwise to a mixture of 30 ml. of 35% nitric acid at room temperature. After stirring overnight, the reaction mixture was diluted with water and made basic with sodium carbonate. The product was extracted into ethyl acetate, which, after drying over potassium carbonate was evaporated to yield 5.3 g of 4-(4-fluorophenyl)-5-(3-pyridyl)imidazole.
