실험 절차

Compound 4.5 (32.7 g, 63.0 mmol) was dissolved in THF (250 mL). To the solution was added 4N LiOH (31.5 mL, 126 mmol) and the reaction was stirred at room temperature for 1 h, after which time water (31.5mL) was added, and the reaction mixture was stirred for 30 min. 2N HCl (70 mL) was then added to the reaction and the THF was removed in vacuo. The residue was diluted with hexane (250 mL) with stirring, and the deposited crystals were collected by filtration and recrystallized from EtOAc—hexane to provide 4 (24.12 g). MS APSI m/e: 489 (M−H). 1H NMR (400 MHz) (DMSO-d6) δ 12.90 (1H, brs); 7.76 (2H, d, J=8.2 Hz); 7.67 (2H, d, J=8.2 Hz); 7.20-7.05 (4H, m); 6.99 (1H, d, J=8.6 Hz); 6.81 (1H, d, J=8.4 Hz); 5.23 (2H, s); 4.68 (2H, s); 2.56-2.47 (2H, m); 2.18 (3H, s); 1.60-1.47 (2H, m); 0.85 (3H, t, J=7.4 Hz).
