Versuchsvorschrift

(S)-3-[6-Fluoro-2-oxo-3-(1H-pyrrol-2-yl)-1,2-dihydro-benzo[cd]indol-5-ylsulfanyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (from Example 56 above) (54 mg, 0.12 mmol) was dissolved at 0° C. in a 50% TFA in CH2Cl2 solution (6 mL) that contained H2O (0.3 mL). After 2 hours the reaction mixture was partitioned between ethyl acetate and aqueous 1 N NaOH. The pH of the aqueous layer was adjusted to 14. The aqueous layer was extracted twice with ethyl acetate and the combined organic layer was washed with H2O, dried over Na2SO4, filtered, and concentrated to dryness. The residue was purified by a precipitation out of THF with excess of pentane to give 6-fluoro-5-[(S)-(pyrrolidin-3-ylsulfanyl)]-3-(1H-pyrrol-2-yl)-1H-benzo[cd]indol-2-one as a yellow solid. (Yield 41 mg; 97%).
