실험 절차

To a solution of (1E,6E)-1-[4-(tert-butoxycarbonylamino)phenyl]-7-(4-hydroxyphenyl)hepta-1,6-diene-3,5-dione (22 mg, 54 μmol, synthesized in Example 278) in 1 mL of tetrahydrofuran was added 2 mL of 4N HCl/dioxane at room temperature. After being stirred at the same temperature for 1 h, the reaction mixture was neutralized with saturated NaHCO3 aqueous solution. The mixture was extracted with chloroform, and the organic layer was dried over Na2SO4. After filtration, the filtrate was concentrated in vacuo and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=70/30 to 50/50) to obtain the title compound as a solid (5.8 mg, 35%) having the following characteristics.
