Potassium Carbonate → 2-(2-Fluorophenyl)-1-hydroxy-4-methyl-5-(3-pyridyl)imidazole

Participants

Reaction Steps

To a solution 1-hydroxyimino-1-(3-pyridyl)acetone (0.5 g) in acetic acid (10 ml) was added 2-fluorobenzaldehyde (0.76 g) and ammonium acetate (2.35 g), and refluxed for 30 minutes. Then, the solution was poured into water (75 ml), neutrallized with aqueous potassium carbonate, and extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated, and the residue was triturated with diisopropyl ether to give 2-(2-fluorophenyl)-1-hydroxy-4-methyl-5-(3-pyridyl)imidazole (0.23 g).
