Reaction Steps

The title compound was synthesized using the same procedure employed for Example 281, but with (1E,6E)-1-[1-(tert-butoxycarbony)-indolin-6-yl]-7-(4-hydroxyphenyl)hepta-1,6-diene-3,5-dione (14 mg, 32 μmol, synthesized in Example 292) as the starting material instead of (1E,6E)-1-[4-(tert-butoxycarbonylamino)phenyl]-7-(4-hydroxyphenyl)hepta-1,6-diene-3,5-dione, and was purified by silica gel chromatography (chloroform/methanol=100/0 to 95/5). The product was obtained as a solid (1.4 mg, 13%) having the following characteristic.
