실험 절차

1-Hydroxymethyl-3-(1-methyl-1H-indol-3-yl)-4-(1-methyl-6-nitro-1H-indol-3-yl)-pyrrole-2,5-dione (200 mg, 0.47 mmol), prepared as in example 1a, was dissolved in THF (10 mL). The resulting red solution was cooled in an ice bath. Lithium bis(trimethylsiliyl)amide (0.56 mL, 0.56 mmol, 1 M in THF) was added dropwise to the solution to give a red suspension. After 10 min, bis(p-nitrophenyl)carbonate (200 mg, 0.66 mmol) was added. The resulting solution was stirred at 0° C. for 20 min. Diethylaminoethylamine (90 mg, 0.78 mmol) in THF (2 mL) was added. Stirring was continued for 2 hrs. The mixture was evaporated and the residue was purified by flash chromatography to give (2-dimethylamino-ethyl)-carbamic acid 3-(1-methyl-1H-indol-3-yl)-4-(1-methyl-6-nitro-1H-indol-3-yl)-2,5-dioxo-2,5-dihydro-pyrrol-1-ylmethyl ester (124 mg 46%).
