実験手順
A solution of the compound (55 mg) obtained in Step 7 in trifluoroacetic acid (330 μl) was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure, chloroform was added to the residue, and the mixture was concentrated again under reduced pressure. The residue was purified by thin layer chromatography (methanol:chloroform=1:10) to give the title compound (43 mg).
