Sodium Carbonate → Ethyl cis(+/-)-2-[4-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-ethoxypiperidin-1-yl)-2-oxopyridin-1(2H)-yl]-4-methyl-1,3-thiazole-5-carboxylate

Participants

Reaction Steps

cis(±)-4-Chloro-N-(3-ethoxypiperidin-4-yl)-5-ethyl-1H-imidazole-2-carboxamide hydrochloride obtained in Example (131a) (100 mg, 0.297 mmol), ethyl 2-(4-chloro-2-oxopyridin-1(2H)-yl)-4-methyl-1,3-thiazole-5-carboxylate obtained in Example (140a) (106 mg, 0.355 mmol) and sodium carbonate (157 mg, 1.48 mmol) were suspended in DMSO (1 mL). The suspension was subjected to same operation as in Example (131b) to obtain 10.8 mg of the title compound as a pale yellow solid (6%).
