실험 절차

The oil obtained in Example 142 was dissolved in methanol (5 mL) and tetrahydrofuran (5 mL), and 2 N aqueous sodium hydroxide solution (2 mL) was added. The mixture was stirred at room temperature for 1 hr. The reaction mixture was neutralized with 6 N hydrochloric acid, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was dried using a Presep Dehydration tube (Manufactured by Wako Pure Chemical Industries, Ltd.), and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=9:1-1:4) to give the title compound (61 mg, yield 11%, 2 steps) as colorless crystals. 1H NMR (CDCl3) δ: 2.62 (2H, t, J=7.5 Hz), 2.79-2.93 (6H, m), 4.98 (2H, s), 5.24 (2H, s), 6.37 (1H, s), 6.59-6.68 (2H, m), 7.03-7.14 (7H, m), 7.18-7.38 (5H, m), 7.76 (2H, dd, J=8.9, 5.5 Hz).
