Procedimiento

To a solution of triphenylphosphine (422 mg, 1.61 min ol, 1.30 equivalents) and imidazole (219 mg, 3.22 mmol, 2.60 equivalents) in anhydrous tetrahydrofuran (10 ml) add iodine (410 mg, 1.61 mmol, 1.30 equivalents). After stirring for 20 minutes at room temperature under nitrogen, add N-{3-[5-Fluoro-1-(3-hydroxy-propyl)-indan-1-yl]-1H-indol-7-yl}-methanesulfonamide (500 mg, 1.24 mmol) and stir for 48 hours. Dilute with ether, wash with water (2×), wash with 1N aqueous hydrochloric acid (2×), dry over anhydrous sodium sulfate, filter, and concentrate the solution. Purify the residue on silica eluting with 50 to 100% ethyl acetate/hexanes over 25 minutes to obtain the title compound as a white solid (254 mg, 40%). LC-MS m/z 385.0 (M+−I).
