Versuchsvorschrift
The same operation as in Example (42f) was performed using tert-butyl cis(±)-3-(4-{[(5-ethyl-4-trifluoromethyl-1H-imidazol-2-yl)carbonyl]amino}-3-ethoxypiperidin-1-yl)benzoate obtained in Example (48f) (80 mg, 0.16 mmol) and trifluoroacetic acid (1 ml), to obtain 61.1 mg of the title compound (86%).
