Procedure

3-Fluoro-4-{3-[(1S)-2-methoxy-1-methylethoxy]-5-[5-(1,3-thiazol-2-yl)-1H-pyrrol-2-yl]phenoxy}benzoic acid (40.0 mg, 0.085 mmol) synthesized in Example (44a) was dissolved in tetrahydrofuran (5 mL), and pyrrolidine (21 μL, 0.26 mmol), HATU (64.9 mg, 0.171 mmol) and N,N-diisopropylethylamine (89 μL, 0.51 mmol) were added, followed by stirring at room temperature for 20 hours under nitrogen atmosphere. To the reaction solution, saturated brine (15 mL) was added, and extraction was carried out twice with ethyl acetate (15 mL), followed by drying over sodium 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=0%-75%) to afford the desired compound (32 mg, yield 72%) as a white solid.
