실험 절차

To a cold (0° C.) solution of 257 (458 mg, 1.0 mmol) in dichloromethane (25 mL) is added TFA (1.5 mL). The reaction mixture is stirred for 20 min. at 0° C., and at RT for 30 min. The solution is poured into cold sat. sodium bicarbonate solution, and the mixture extracted with EtOAc. The organic layer is separated, dried (MgSO4), and filtered. The filtrate is rotary evaporated, and the residue is recrystallized from Et2O to give 170 mg of the product 258. 1H NMR (CDCl3) δ 10.60-8.80 (bs, 1 H), 8.00-7.80 (m, 2 H), 7.20-7.00 (m, 9 H), 7.00-6.85 (m, 4 H), 5.50 (bs, 1 H), 5.30 (s, 2 H); MS: m/z 359 (M++1).
