Procedure

5-{3-[(1S)-2-Methoxy-1-methylethoxy]-5-[4-(methylsulfonyl)phenoxy]phenyl}-1H-pyrrole-2-carboxylic acid (300 mg, 0.673 mmol) synthesized in Example (18a) was dissolved in dichloromethane (10 mL), and 1-amino-2-methyl-2-propanol (150 mg, 1.68 mmol), WSCI.HCl (185 mg, 0.965 mmol) and 4-dimethylaminopyridine (165 mg, 1.35 mmol) were added, followed by stirring at room temperature for 17 hours under nitrogen atmosphere. 1N hydrochloric acid (10 mL) was added, and the solution was separated with dichloromethane (15 mL). The organic layer was washed with 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=60%-100%) to afford the desired product (307 mg, yield 88%) as a white solid.
