실험 절차

tert-Butyl (E)-(2S,3S)-3-[(S)-2-(4-but-2-ynyloxy-phenyl)-1-methoxycarbonyl-ethylcarbamoyl]-12,12-difluoro-2-hydroxy-2-(2-methoxy-ethyl)-nonadec-4-enoate (No. 6804236; 28.9 mg, 0.0393 mmol) was dissolved in dichloromethane (3.0 mL), and trifluoroacetic acid (1.0 mL) was added. The mixture was stirred at room temperature for 15 hours. The solvent was distilled off under reduced pressure. To the residue was added dichloromethane, and the solvent was again distilled off under reduced pressure. This operation was repeated twice and the residue was then purified by HPLC (water with 0.05% TFA-acetonitrile with 0.05% TFA) to obtain (E)-(2S,3S)-3-[(S)-2-(4-but-2-ynyloxy-phenyl)-1-methoxycarbonyl-ethylcarbamoyl]-12,12-difluoro-2-hydroxy-2-(2-methoxy-ethyl)-nonadec-4-enoic acid (No. 5513213; 20.1 mg, 75% yield, white powder).
