Procedure

2-(5-{3-(2-Fluoro-4-{[3-(tetrahydro-2H-pyran-2-yloxy)azetidin-1-yl]carbonyl}phenoxy)-5-[(1S)-2-methoxy-1-methylethoxy]phenyl}-1H-pyrrol-2-yl)-1,3-thiazole (110 mg, 0.181 mmol) synthesized in Example (42b) was dissolved in methanol (10 mL), and 10-camphorsulfonic acid (20 mg, 0.086 mmol) was added, followed by stirring at room temperature overnight under nitrogen atmosphere. To the reaction solution, triethylamine (0.1 mL) was added, and the solvent was distilled off under reduced pressure. The resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=90%-100%) to afford the desired compound (62 mg, yield 65%) as a yellow solid.
