Procedure

5-{3-[(1S)-2-Methoxy-1-methylethoxy]-5-[5-(1,3-thiazol-2-yl)-1H-pyrrol-2-yl]phenoxy}pyrazine-2-carboxylic acid (28.0 mg, 0.062 mmol) synthesized in Example (63a) was dissolved in tetrahydrofuran (3 mL), and azetidine hydrochloride (17.4 mg, 0.186 mmol), HATU (35.3 mg, 0.093 mmol) and N,N-diisopropylethylamine (65 μL, 0.37 mmol) were added, followed by stirring at room temperature for 28 hours under nitrogen atmosphere. To the reaction solution, water (15 mL) was added, and extraction was carried out 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 preparative TLC (developing solvent: methanol/dichloromethane=15%) to afford the desired compound (29.1 mg, yield 96%) as a white solid.
