Versuchsvorschrift

tert-Butyl cis(±)-{(5Z)-5-[2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)-2-oxoethylidene]-2,4-dioxo-1,3-thiazolidin-3-yl}acetate obtained in Example (163a) (20.4 mg, 0.04 mmol) was dissolved in methanol (4 mL). A 20% trifluoroacetic acid-dichloromethane solution (5 ml) was added, and the mixture was stirred at room temperature. The organic solvent was evaporated under reduced pressure, and then the residue was washed with ether. The solid was collected by filtration to obtain 7.79 mg of the title compound as a white solid (43%).
