実験手順

(3-Nitrophenyl)boronic acid (0.086 g, 0.52 mmol) was mixed with N-(5-iodo-6-methylpyridin-3-yl)-3-(trifluoromethyl)benzamide (0.21 g, 0.52 mmol) and potassium carbonate (0.13 g, 0.91 mmol) in toluene (3.8 mL), ethanol (0.56 mL) and water (0.5 mL) and the solution was degassed. Into the reaction was added tetrakis(triphenylphosphine)palladium(0) (0.025 g, 0.022 mmol) and was refluxed for 18 hours. The reaction was extracted with EtOAc and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and stripped in vacuo. The residue was purified by column chromatography using 40% EtOAc/hexanes to give the product (0.156 g, 75% yield). 1H NMR (400 MHZ, CDCl3): δ 8.67 (d, 1H), 8.28 (m, 2H), 8.16 (brs, 1H), 8.11 (m, 1H), 7.99 (brs, 1H), 7.85 (m, 1H), 7.69 (m, 4H), 2.52 (s, 3H); MS (ES) (M+H)=402.
