실험 절차

The same operation as in Example (158a) was performed using cis(±)-4-chloro-5-ethyl-N-(3-methoxypiperidin-4-yl)-1H-imidazole-2-carboxamide hydrochloride obtained in Example (159a) (62.51 mg, 0.19 mmol), methyl 2-fluoropyridine-3-carboxylate (68 mg, 0.39 mmol) and diisopropylethylamine (75 mg, 0.58 mmol), to obtain 65.2 mg of the title compound as a yellow brown oily substance (80%).
