HCID 86648498tert-Butyl cis(+/-)-3-(4-{[(5-ethyl-4-trifluoromethyl-1H-imidazol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)benzoateYield 67%

Procedure

The same operation as in Example (1g) was performed using tert-butyl cis(±)-3-(4-amino-3-methoxypiperidin-1-yl)benzoate obtained in Example (42d) (about 0.26 mmol), 5-ethyl-4-(trifluoromethyl)-1H-imidazole-2-carboxylic acid obtained by the method described in Example (39e) (50 mg, 0.24 mmol), WSC hydrochloride (137 mg, 0.71 mmol) and HOBT (32 mg, 0.24 mmol), to obtain 79.7 mg of the title compound as a white solid (67%).
