Participants

Reaction Steps

The same operation as in Example (1h) was performed using cis(±)-4-chloro-N-(3-isopropoxypiperidin-4-yl)-5-ethyl-1H-imidazole-2-carboxamide hydrochloride obtained in Example (148a) (0.150 g, 0.427 mmol), diisopropylethylamine (0.186 mL, 1.07 mmol) and ethyl 2-chloro-4-[(2-methoxyethyl)carbamoyl]-1,3-thiazole-5-carboxylate obtained in Example (149a) (0.167 g, 0.572 mmol), to obtain 0.180 g of the title compound as a yellow solid (74%).
