Reaction Steps

To a solution of 4-(5-Fluoro-2-pyridyl)-1-trityl-1H-imidazole (0.23 g, 0.56 mmol) in tetrahydrofuran (4 ml) added hydrochloric acid (2.4 ml, 2N aqueous). The resulting reaction mixture was heated at reflux for 45 min. The reaction mixture was cooled to room temperature and concentrated in-vacuo. The isolated residue was triturated with diethyl ether to yield 4-(5-Fluoro-2-pyridyl)imidazole (0.06 g) as the hydrochloride salt.
