Reaction Steps

A solution of PdCl2(dppf)-CH2Cl2 adduct (0.233 g, 0.285 mmol), 1-methyl-2-(tributylstannyl)imidazole (2.189 ml, 6.84 mmol), 1-bromo-2-iodo-4-(trifluoromethyl)benzene (0.919 ml, 5.70 mmol), and potassium fluoride (1.656 g, 28.5 mmol) in 6 mL DMF was heated to 80° C. overnight. LC/MS showed product, so the reaction mixture was poured into water and was extracted with DCM. The organics were dried over MgSO4 and concentrated. Purification of the crude residue by silica gel column chromatography (0 to 100% EtOAc/heptane) gave 2-(2-bromo-5-(trifluoromethyl)phenyl)-1-methyl-1H-imidazole (1.122 g, 3.68 mmol, 64.5% yield). m/z (ESI) 307.2 (M+H)+.
