Reaction Steps

The title compound was synthesized using the same procedure employed for Example 281, but with (1E,6E)-1-(4-hydroxyphenyl)-7-[4-((R)-2-tert-butoxycarbonylamino-3-phenylpropionylamino)phenyl]hepta-1,6-diene-3,5-dione (30 mg, 54 μmol, synthesized in Example 279) 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=97/3 to 85/15). The product was obtained as a solid (9.2 mg, 37%) having the following characteristics.
