実験手順

4,4,5,5-Tetramethyl-2-(3-nitrophenyl)-1,3,2-dioxaborolane (0.40 g, 0.0016 mol) was mixed with 4-chloro-3-iodo-N-[3-(trifluoromethyl)phenyl]benzamide (0.600 g, 0.00141 mol), potassium carbonate (0.39 g, 0.0028 mol), toluene (10 mL), ethanol (1.7 mL), and water (1.1 mL). The mixture was degassed by bubbling nitrogen through it. To the reaction was added tetrakis(triphenyl-phosphine)palladium(0) (0.078 g, 0.000068 mol). The reaction was heated to reflux for 16 hours. LCMS showed about 80% conversion to M+H 421/423 (3:1). The reaction was extracted with ethyl acetate and the organic extracts were washed with water, saturated NaCl, then dried (Na2SO4). Solvent was removed under vacuum to give 0.87 g oil. The product was purified by automatic flash chromatography on silica gel. Used a 40 g column; flow 40 mL/min; [A=hexane] [B=EtOAc]. A, 4 min; Gradient to 20% B in 30 min. The product eluted in 23-28 min (starting material at 16-18 min). Removal of solvent under vacuum gave 0.46 g white solid.
