Reaction Steps

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) (104 mg, 0.32 mmol), methyl 6-fluoropyridine-3-carboxylate (50 mg, 0.32 mmol) and diisopropylethylamine (125 mg, 0.97 mmol), to obtain 130 mg of the title compound as a yellow brown oily substance (96%).
