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) (200 mg, 0.40 mmol), 2-amino-1-propanol (0.06 mL, 0.80 mmol), WSC hydrochloride (230 mg, 1.20 mmol) and 1-hydroxybenzotriazole (54 mg, 0.40 mmol), to obtain 144 mg of the title compound as a white solid (65%).
