Procedure

2-[(R)-2-(7-cyclopentylamino-5-methanesulfonylmethyl-1H-indol-2-yl)-4,5-dihydro-thiazol-4-yl]-ethanol (178 mg, 0.42 mmol) prepared in Example 99 was dissolved in tetrahydrofuran (10 mL). Iodine (161 mg, 0.63 mmol), triphenylphosphine (166 mg, 0.63 mmol) and imidazole (86 mg, 1.23 mmol) were added thereto, and the mixture was stirred for 8 h at room temperature. The reaction was quenched by water, and the reaction mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium chloride solution, 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 (120 mg, Yield 54%).
