Procedure

The same operation as in Example (1g) was performed using ethyl cis(±)-2-(4-amino-3-methoxypiperidin-1-yl)-5-methylpyridine-4-carboxylate obtained in Example (180b) (26.1 mg, 0.09 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (14.8 mg, 0.08 mmol), WSC hydrochloride (48.8 mg, 0.25 mmol) and HOBt (11.5 mg, 0.08 mmol), to obtain 28.8 mg of the title compound as a yellow oily substance (76%).
