Procedure

4-{3-[(1S)-2-Methoxy-1-methylethoxy]-5-[5-(1,3-thiazol-2-yl)-1H-pyrrol-2-yl]phenoxy}-3-methylbenzoic acid (58 mg, 0.125 mmol) synthesized in Example (53a) and azetidine hydrochloride (29 mg, 0.310 mmol) were dissolved in dichloromethane (10.0 mL), and HATU (95 mg, 0.250 mmol) and N,N-diisopropylethylamine (0.15 mL, 0.861 mmol) were added, followed by stirring at room temperature overnight under nitrogen atmosphere. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=75%-90%) to afford the desired compound (58 mg, yield 92%) as a yellow solid.
