Versuchsvorschrift

5-{3-[4-(Azetidin-1-ylcarbonyl)-2-fluorophenoxy]-5-[(1S)-2-methoxy-1-methylethoxy]phenyl}-1H-pyrrole-2-carboxylic acid (66 mg, 0.15 mmol) synthesized in Example (66g), 2-chloroethylamine hydrochloride (34 mg, 0.30 mmol) and 4-dimethylaminopyridine (18 mg, 0.15 mmol) were dissolved in dichloromethane (10 mL), and WSCI.HCl (31 mg, 0.16 mmol) was added at room temperature, followed by stirring for 1 hour under nitrogen atmosphere. The reaction solution was diluted with dichloromethane (60 mL), washed with 1N hydrochloric acid, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and subsequently dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=30%-60%) to afford the desired product (56 mg, yield 79%) as a white solid.
