実験手順
A suspension of 2-chloro-5-[4-(3,4-dichloro-phenyl)-1H-imidazol-2-yl]-pyridine dihydrochloride (1.07 g, 2.6 mmol), N-isobutylpiperazine (0.95 g, 6.72 mmol), potassium carbonate (0.5 g, 3.62 mmol), and potassium iodide (0.5 g, 0.54 mmol) in xylenes (5 mL) was heated to reflux under a nitrogen atmosphere for 24 hours. The reaction mixture was then cooled to ambient temperature and a solution of potassium carbonate (19) in water (10 mL) and cyclohexane (10 mL) were added. The mixture was stirred vigorously for 15 min, and the precipitate was collected by filtration. The filter cake was washed with water (10 mL) and triturated with methyl tert-butyl ether (4 mL) to provide 1-{5-[5(3,4-dichloro-phenyl)-1H-imidazol-2-yl]-pyridin-2-yl}-4-isobutyl-piperazine (2.07 mmol).
