Reaktionsschritte

(3-Nitrophenyl)boronic acid (1.7 g, 10.0 mmol) was mixed with 3-fluoro-N-(3-iodo-4-methylphenyl)-5-(trifluoromethyl)benzamide (4.30 g, 10.2 mmol) and potassium carbonate (2.5 g, 18 mmol) in toluene (75.00 mL), ethanol (11.00 mL) and water (10.00 mL) and was degassed. To the mixture was added tetrakis(triphenylphosphine)palladium(0) (0.50 g, 0.43 mmol) and the resulting mixture was heated to reflux for 18 hours. The reaction was extracted with ethyl acetate and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and then concentrated in vacuo. The residue was purified by column chromatography using 20% EtOAc/hexanes to give the product (4.09 g, 96% yield). MS (EI) m/z=419 (M+H).
