実験手順
A suspension of (4-(3-aminophenyl)piperazin-1-yl)(phenyl)methanone (0.5 g, 1.8 mmol), copper acetate (0.65 g, 3.6 mmol), triethylamine (1.7 ml, 12.4 mmol), 4 Å molecular sieves (0.5 g) and phenylboronic acid and pyridine complex (0.70 g, 1.8 mmol) in 30 ml dry dichloromethane was stirred at room temperature overnight. The reaction was quenched with 20 ml water extracted with dichloromethane (3×40 ml), followed by drying over anhydrous sodium sulfate. 3-(4-Benzoylpiperazin-1-yl)-N-phenylbenzenamine (0.42 g, 66%) was obtained by flash column chromatograph (50% ethyl acetate in hexanes). 1H NMR (500 MHz, CDCl3) δ (ppm) 3.20 (d, br, 4H), 3.65 (d, br, 4H), 5.73 (s, 1H), 6.54 (dd, J=8.0, 1.6 Hz, 1H), 6.67 (m, 2H), 6.97 (t, J=7.4 Hz, 1H), 7.11 (dd, J=8.6, 1.0 Hz, 2H), 7.28 (t, J=8.0 Hz, 1H), 7.44 (m, 2H), 7.48 (m, 5H). 13C NMR (125 MHz, CDCl3): δ (ppm) 50.0, 50.1, 50.3, 106.5, 110.0, 110.7, 118.6, 121.6, 127.6, 129.0, 129.8, 130.3, 130.5, 136.1, 143.5, 144.7, 152.6, 170.9.
