Procedure

Benzyl 5-(3-[(1S)-2-methoxy-1-methylethoxy]-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}phenyl)-1H-pyrrole-2-carboxylate (5.08 g, 9.47 mmol) synthesized in Example (78j) was dissolved in ethyl acetate (30 mL), and a 10% palladium carbon catalyst (1.10 g) was added, followed by stirring at room temperature for 3 hours under hydrogen atmosphere. After Celite filtration, the solvent was distilled off under reduced pressure to afford the desired compound (4.30 g, yield ˜100%) as a white solid.
