To a solution of (1E,6E)-1-(4-dimethylaminophenyl)-7-(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione (15 mg, 41 μmol, synthesized in Example 9) in 3.0 mL of ethyl acetate was added palladium 5% on carbon (30 mg) under nitrogen. After the vessel was purged with hydrogen, the reaction mixture was stirred under 1 atm of hydrogen at room temperature for 1.5 h. After the vessel was purged with nitrogen, the reaction mixture was filtered to remove palladium 5% on carbon. The filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=75/25 to 65/35) to obtain the title compound as a gum (8.0 mg, 53%) having the following characteristics.
