실험 절차

To a mixture of (S)-3-mercapto-pyrrolidine-1-carboxylic acid tert-butyl ester (from Example 55 above) (1.35 g, 5.81 mmol) and (Z)-5-fluoro-4-[1-iodo-3-oxo-3-(1H-pyrrol-2-yl)-propenyl]-1,3-dihydro-indol-2-one (from Example 8 above) (100 mg, 0.20 mmol) was added NaH (48 mg, 2.01 mmol) in small portions at room temperature. After the evolution of hydrogen ceased, the mixture was heated to 120° C. for 1 hour then cooled and partitioned between ethyl acetate and water. The water layer was extracted with ethyl acetate (3×) and the combined organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by HPLC (silica gel, 25% ethyl acetate in hexanes) followed by a precipitation out of THF with excess of pentane to give (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 as a yellow solid. (Yield 57 mg; 62%).
