Reaction Steps

To a stirred solution of (4-(3-amino-4-methoxyphenyl)piperazin-1-yl) (phenyl)methanone (2 g, 6.4 mmol) and phenylboronic acid (2.34 g, 19.2 mmol) in DCM (100 mL) was added triethylamine (2.7 mL, 19.2 mmol) and Cu(OAc)2 (1.74 g, 9.6 mmol). The mixture was stirred for 12 h. It was then filtered through celite, evaporated under vacuum. Flash column chromatography gave (4-(4-methoxy-3-(phenylamino) phenyl)piperazin-1-yl)(phenyl)methanone (2.0 g), 80% yield. 1H NMR (500 MHz, CDCl3): δ 3.0 (bs, 2H), 3.15 (bs, 2H), 3.59 (bs, 2H), 3.89 (s, 3H), 3.95 (bs, 2H), 6.18 (s, 1H), 6.46 (dd, J=2.5, 3 Hz 1H), 6.85 (d, J=9 Hz, 1H), 7.01 (m, 2H), 7.19 (d, J=7.5 Hz, 2H), 7.34 (m, 2H), 7.49 (m, 5H).
