실험 절차

Compound 12 (0.05 mg, 0.12 mmol) was dissolved one equivalent of 1N NaOH. The solution was allowed to stir at Rt for 2 h, then acidified to pH 4. The resulting precipitate was filtered and washed with water and ether. 1HNMR (CD3OD) Δ3.75 (m, 1H), 3.90 (m, 1H), 4.13 (d, 1H), 4.43 (d, 1H), 4.64 (m, 1H), 6.05 (d, 1H), 8.10 (s, 1H), 8.35 (s, 1H), 9.05 (s, 1H).
