反応手順
The same operation as in Example (196b) was performed using tert-butyl cis(±)-4-amino-3-chloropiperidine-1-carboxylate obtained in Example (198a) (134 mg, 0.571 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained in Example (1d) (99.7 mg, 0.571 mmol), 1-hydroxybenzotriazole hydrate (116 mg, 0.856 mmol), WSC hydrochloride (164 mg, 0.856 mmol) and triethylamine (119 μL, 0.856 mmol), to obtain 164 mg of the title compound (73%) as a colorless solid.
