실험 절차

[step 1] 4-Iodo-2-propylimidazole obtained in Reference Example A16 was dissolved in dioxane/water (2 mL/1 mL), 4-pyridineboronic acid (0.108 g, 0.889 mmol), 1,1-bisdiphenylphosphinoferrocene dichloropalladium (0.052 g, 0.064 mmol) and sodium carbonate (0.202 g, 1.91 mmol) were added, and the mixture was heated under reflux for 3 hr. The reaction mixture was concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/2) to give 2-propyl-4-(4-pyridyl)imidazole (0.044 g, 37%).
