Versuchsvorschrift

2-[(R)-2-(5-chloro-7-cyclopentylamino-1H-indol-2-yl)-4,5-dihydro-thiazol-4-yl]-ethanol (50 mg, 0.11 mmol) prepared in Example 5 was dissolved in N,N-dimethylformamide (2 mL). Sodium methanesulfonate (54 mg, 0.55 mmol) was added thereto, and the mixture was stirred for 8 h at room temperature. The reaction was quenched by water. The reaction mixture was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under reduced pressure, and the residue was purified by column chromatography to give the title compound (19 mg, Yield 45%).
