Versuchsvorschrift

Ethylamine (2.0 M solution in THF) (0.60 mL, 1.20 mmol), WSC hydrochloride (345 mg, 1.80 mmol) and 1-hydroxybenzotriazole (8 1 mg, 0.60 mmol) were added to a mixed solution of 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) (300 mg, 0.60 mmol) in DMA/dichloromethane (6 mL/6 mL) at room temperature, followed by stirring for five hours. The reaction solution was diluted with ethyl acetate, and then the mixture was washed with a 1 N aqueous hydrochloric acid solution and 5% saline. The organic layer was dried over anhydrous magnesium sulfate. Following filtration, the filtrate was concentrated under reduced pressure. The resulting residue was suspended and washed in diethyl ether to obtain 257 mg of the title compound as a white solid (81%).
