Procedure

The same operation as in Example (1g) was performed using ethyl cis(±)-[2-(4-amino-3-methoxypiperidin-1-yl)-1,3-thiazol-4-yl]acetate obtained in Example (64d) (about 0.29 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (45 mg, 0.26 mmol), WSC hydrochloride (150 mg, 0.78 mmol) and HOBT (35 mg, 0.26 mmol), to obtain 42.6 mg of the title compound (36%).
