Versuchsvorschrift

To a solution of tert-butyl 3-[4-(6-chloro-3-formyl-1H-indol-5-yl)phenyl]pyrrolidine-1-carboxylate (43 mg, 0.1 mmol) in acetonitrile (1.2 mL) and tert-butanol (1.2 mL) was added 2-methyl-2-butene (1.2 mL). The reaction mixture was cooled to 0° C. and treated with a solution of sodium chlorite (100 mg, 1.1 mmol) and sodium phosphate monobasic dihydrate (234 mg, 1.5 mmol) in water (0.6 mL). After the resulting mixture was stirred for 2 h at room temperature, additional sodium chlorite (134 mg, 1.47 mmol) and sodium phosphate monobasic dihydrate (312 mg, 2.0 mmol) in H2O (0.6 mL) was added to the reaction mixture. The resulting mixture was stirred at room temperature for 16 h. The reaction mixture was concentrated in vacuo and the aqueous residue was extracted with EtOAc (3×20 mL). The combined organic layers were dried over Na2SO4 and concentrated in vacuo. The residue was dissolved in DMSO and purified via pre-HPLC to give 5-{4-[1-(tert-butoxycarbonyl)pyrrolidin-3-yl]phenyl}-6-chloro-1H-indole-3-carboxylic acid (16 mg, 36%) as a white solid. MS (ES+) 463.1 (M+Na)+.
