실험 절차

A mixture of 5 (60 mg, 0.075 mmol), Pd(PPh3)4 (17 mg, 0.015 mmol), CsF (34 mg, 0.22 mmol), 3-hydroxyphenylboronic acid (16 mg, 0.12 mmol), and H2O (80 μL) in DME (8 mL) was degassed with N2 for 10 min and then refluxed. When the reaction was over by TLC monitoring, the mixture was poured into H2O (10 mL) and then extracted with 70 mL Et2O. The organic layer was washed with brine (2×10 mL), dried over MgSO4, and then concentrated in vacuo. MPLC purification (Hex:EtOAc/5:1) of the residue gave 6 as a yellow amorphous solid (50 mg, 82%). 1H NMR (400 MHz, CDCl3) δ 8.13 (d, J=8.0 Hz, 2H), 8.04 (s, 1H), 7.74-7.61 (m, 7H), 7.56 (d, J=8.0 Hz, 2H), 7.49-7.26 (m, 6H), 7.13 (s, 1H), 7.03 (d, J=7.6 Hz, 1H), 6.92 (d, J=8.4 Hz, 1H), 6.63 (s, 1H), 5.40 (s, 2H), 4.32 (t, J=7.2 Hz, 2H), 4.16-4.06 (m, 2H), 3.72 (s, 2H), 3.51 (t, J=6.8 Hz, 2H), 1.72-1.69 (m, 2H), 1.49-1.46 (m, 2H), and 1.26 (t, J=7.2 Hz, 3H); 13C NMR (100 MHz, CDCl3) δ 188.62, 171.45, 168.65, 166.21, 157.16, 149.47, 143.69, 141.59, 138.00, 137.26, 137.23, 136.09, 134.28, 131.99, 131.82, 130.66, 130.37, 130.33, 130.12, 129.33, 128.90, 128.62, 128.53, 123.49, 121.88, 121.13, 120.87, 116.54, 116.46, 112.82, 104.20, 67.20, 61.46, 43.92, 37.36, 34.81, 27.45, 25.84, and 14.42.
