Procedure

cis(±)-4-Chloro-N-(3-ethoxypiperidin-4-yl)-5-ethyl-1H-imidazole-2-carboxamide hydrochloride obtained in Example (131a) (100 mg, 0.297 mmol), 4-chloro-2-hydroxypyridine (46 mg, 0.36 mmol) and sodium carbonate (157 mg, 1.48 mmol) were suspended in DMSO (1 mL). The suspension was subjected to the same operation as in Example (131b) to obtain 6.3 mg of the title compound as a pale yellow amorphous solid (5%).
