Reaction Steps
Lithium aluminum hydride (22 mg, 0.580 mmol) was suspended in tetrahydrofuran (2 mL). Ethyl 2-(5-{3-[(1S)-2-methoxy-1-methylethoxy]-5-[4-(methylsulfonyl)phenoxy]phenyl}-1H-pyrrol-2-yl)-1,3-thiazole-5-carboxylate (106 mg, 0.190 mmol) synthesized in Example (5c) was dissolved in tetrahydrofuran (2 mL), followed by dropwise addition at 0° C. under nitrogen atmosphere. After stirring at 0° C. for 30 minutes, water (22 μL) and an aqueous sodium hydroxide solution (5M, 88 μL) were added dropwise sequentially and slowly. After filtration through Celite, the solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=50%-100%) to afford the desired compound (48 mg, yield 49%) as a pale yellow solid.
