Versuchsvorschrift

(E)-N1-(3-(1H-imidazol-1-yl)propyl)-2-((naphthalen-1-yloxy)-methyl)-N8-(tetrahydro-2H-pyran-2-yloxy)-2-octenediamide (203 mg, 0.38 mM) obtained in Example (2-1-3) was dissolved in methanol (2 ml), and trifluoroacetic acid (146 μl, 1.90 mM) was slowly added thereto at 0° C. Then, the resulting mixture was heated to room temperature and reacted for 18 hrs. After the completion of reaction, the solvent was removed under reduced pressure. The residue thus obtained was subjected to a silica gel column chromatography (eluent: methanol/dichloromethane=1/9) to obtain 63 mg of the title compound (yield 37%).
