Procedure

Methyl 2-(5-{3-[(1S)-2-methoxy-1-methylethoxy]-5-[4-(methylsulfonyl)phenoxy]phenyl}-1H-pyrrol-2-yl)-4,5-dihydro-1,3-oxazole-5-carboxylate (60.5 mg, 0.114 mmol) synthesized in Example (27b) was dissolved in ethanol (4 mL). An aqueous sodium hydroxide solution (5M, 2 mL) was added, and stirring was carried out at 70° C. for 2.5 hours. After cooling to room temperature, hydrochloric acid (2M, 5 mL) and ethyl acetate (10 mL) were added, and the solution was separated. The organic layer was washed with saturated brine, and subsequently dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to afford the desired compound (69.3 mg, yield ˜100%) as a pale yellow solid.
