실험 절차
t-Butyl 2-{3-hydroxy-5-[(1S)-2-methoxy-1-methylethoxy]phenyl}-5-(1,3-thiazol-2-yl)-1H-pyrrole-1-carboxylate (485 mg, 1.127 mmol) synthesized in Example (38d) and commercially available methyl 3,4-difluorobenzoate (540 mg, 3.137 mmol) were dissolved in dimethyl sulfoxide (10 mL), and sodium hydride (60%, 180 mg, 4.50 mmol) was added, followed by stirring at 100° C. for 2.5 hours under nitrogen atmosphere. The reaction solution was cooled to room temperature, water (50 mL) was added, and extraction was carried out with diethyl ether (50 mL). The organic layer was washed with saturated brine, and subsequently dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=10%-30%) to afford the desired compound (97 mg, yield 18%) as a white solid.
