実験手順

t-Butyl 2-{3-hydroxy-5-[(1S)-2-methoxy-1-methylethoxy]phenyl}-5-(1,3-thiazol-2-yl)-1H-pyrrole-1-carboxylate (150 mg, 0.348 mmol) synthesized in Example (38d) and 1-(3,4-difluorobenzoyl)-3-(tetrahydro-2H-pyran-2-yloxy)azetidine (220 mg, 0.740 mmol) synthesized in Example (42a) were dissolved in dimethyl sulfoxide (5.0 mL), and sodium hydride (60%, 70 mg, 1.75 mmol) was added, followed by stirring at 100° C. for 1.5 hours under nitrogen atmosphere. The reaction solution was cooled to room temperature, saturated brine (30 mL) was added, and extraction was carried out with ethyl acetate (30 mL). Subsequently, drying was carried out 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=65%-85%) to afford the desired compound (158 mg, yield 75%) as a white solid.
