実験手順

5-{3-[(1S)-2-Methoxy-1-methylethoxy]-5-[4-(methylsulfonyl)phenoxy]phenyl}-1H-pyrrole-2-carboxylic acid (150 mg, 0.34 mmol) synthesized in Example (18a), 2-chloroethylamine hydrochloride (78 mg, 0.68 mmol) and 4-dimethylaminopyridine (41 mg, 0.34 mmol) were dissolved in dichloromethane (15 mL), WSCI•HCl (71 mg, 0.37 mmol) was added at room temperature, and stirring was carried out for 2 hours under nitrogen atmosphere. The reaction solution was diluted with dichloromethane (150 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 (105 mg, yield 62%) as a white solid.
