実験手順

To a solution of the product of Step C (0.95 g, 2 mmol mol) in dichloromethane (5 ml) and acetonitrile (50 ml) was added NBS (0.35 g, 2 mmol mol) in portions at 0° C. After stirring at 5° C. for 12 h, the reaction mixture was concentrated, and the residue was partitioned between dichloromethane and water. The organic layer was separated, washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated to afford the title compound. 1H NMR (400 MHz, CDCl3) δ 7.50 (d, J=7.2 Hz, 1H), 7.40 (d, J=8.4 Hz, 1H), 7.13 (m, 5H), 6.52 (m, 2H), 5.20 (d, J=16.8 Hz, 1H), 4.34 (d, J=16.8 Hz, 1H), 2.65 (s, 3H), 1.24 (s, 9H).
