Procedure

Benzyl 5-(3-[(1S)-2-methoxy-1-methylethoxy]-5-{[5-(methylsulfonyl)pyrazin-2-yl]oxy}phenyl)-1H-pyrrole-2-carboxylate (3.58 g, 6.66 mmol) synthesized in Example (97d) was dissolved in methanol (100 mL), and a 10% palladium carbon catalyst (2.00 g) was added, followed by stirring at room temperature for 3 hours under hydrogen atmosphere. The palladium carbon catalyst was removed by Celite filtration, followed by washing with tetrahydrofuran. The solvent was distilled off under reduced pressure to afford the desired compound (2.56 g, 86%) as a white solid.
