反応手順

The same operation as in Example (247a) was performed using cis(±)-2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-ethoxypiperidin-1-yl)-5-(ethoxycarbonyl)-1,3-thiazole-4-carboxylic acid obtained in Example (50a) (250 mg, 0.50 mmol), 1-methoxy-2-propylamine (0.11 mL, 1.00 mmol), WSC hydrochloride (288 mg, 1.50 mmol) and 1-hydroxybenzotriazole (68 mg, 0.50 mmol), to obtain 228 mg of the title compound as a white solid (80%).
