実験手順

5-{3-[(1S)-2-Methoxy-1-methylethoxy]-5-[(triisopropylsilyl)oxy]phenyl}-1H-pyrrole-2-carboxylic acid (0.89 g, 1.99 mmol) synthesized in Example (106c) was dissolved in methanol (20 mL), and (2R,3R)-3-aminobutan-2-ol (0.41 g, 4.60 mmol) synthesized in Example (88a) and 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride n hydrate (1.20 g, 4.34 mmol) were added, followed by stirring at room temperature for 3 days under nitrogen atmosphere. After the solvent was distilled off under reduced pressure, a saturated aqueous ammonium chloride solution (50 mL) was added, and extraction was carried out with methylene chloride (80 mL). The organic layer was washed with saturated brine, and subsequently dried over anhydrous magnesium sulfate. The resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=60%-80%) to afford the desired compound (722 mg, yield 70%) as a white foam.
