Reaction Steps

To a solution of 5-iodo-2-methyl-4-(trifluoromethyl)-1H-imidazole (1.98 g, 7.2 mmol) in DME (20 mL) and H2O (4 mL) was added K2CO3 (10 g, 71.9 mmol), trivinylboronic anhydride pyridine complex (1.73 g, 7.19 mmol) and Pd(PPh3)4 (830 mg, 0.719 mmol). The resulting reaction mixture was stirred at 80° C. for 3 h. MeOH (100 mL) was then added to the reaction mixture and the mixture was filtered, concentrated in vacuo, and purified by flash chromatography (SiO2, 10% MeOH/CH2Cl2) to obtain 2-methyl-4-(trifluoromethyl)-5-vinyl-1H-imidazole (911 mg, 5.17 mmol, 72% yield) as a brown syrup.
