실험 절차

Add 1N lithium hydroxide (20 mL) to a solution of N-[3-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenyl]-isophthalamic acid methyl ester (1.75 g, 3.79 mmol) in tetrahydrofuran (15 mL) and ethanol (10 mL). Stir overnight at room temperature. Dilute with water. Acidify with 1N hydrochloric acid. Concentrate to remove organic solvents; filter and wash with water several times, then with hexanes. Dry to afford the title compound as an off-white powder (1.54 g, 91%): 1H NMR (DMSO-d6) δ 0.89 (t, 3H), 1.51 (sextet, 2H), 2.58 (s, 3H), 2.63 (t, 2H), 5.27 (s, 2H), 6.74 (d, 1H), 7.20 (d, 1H), 7.40 (t, 1H), 7.65-7.71 (m, 2H), 7.81 (d, 1H), 7.97 (s, 1H), 8.14 (d, 1H), 8.18 (d, 1H), 8.52 (s, 1H), 10.51 (s, 1H), 12.85 (s, 1H), 13.43 (bs, 1H); MS (APCI-neg mode) m/z (rel intensity) 446 (100).
