Procedure

To a stirred solution of the title compound from Step A (83.0 g, 0.13 mol) in dichloromethane (400 mL) was added triethylamine (20 mL) and the resulting mixture was stirred for 3 h. The reaction mixture turned to dark red color. All volatiles were evaporated and the residue was diluted with water and based by NaHCO3. It was then extracted with dichloromethane (3×250 mL). The combined organic layers were washed with water and brine, dried over Na2SO4 and concentrated. The residue was purified by column chromatography with dichloromethane/methanol=20:1 to afford 47.0 g (77%) of the title compound as yellow gum. 1H NMR (400 MHz, CDCl3): δ 8.35 (s, 1H), 7.95 (d, J=8.6 Hz, 2H), 7.63 (d, J=7.8 Hz, 1H), 7.41 (d, J=8.6 Hz, 2H), 7.31 (d, J=8.6 Hz, 1H), 4.55 (d, J=4.7 Hz, 1H), 3.93 (s, 3H), 2.96-2.93 (m, 1H), 2.64-2.53 (m, 2H), 1.71-1.68 (m, 1H), 1.52-1.41 (m, 3H), 0.90 (s, 9H), 0.20 (s, 3H), 0.00 (s, 3H). MS: m/z (ESI) 473 (M+1).
